Critics regard Evans' most important work to be his prints of children's books with from the latter part of the century with
Walter Crane,
Kate Greenaway, and
Randolph Caldecott which revolutionized children's publishing. In 1865, Evans agreed with publishing house
Routledge and Warne to provide
toy books—paperbound books of six pages, to be sold for
sixpence each. They "revolutionized the field of children's books" and lent Evans his association with children's book illustrators. According to Judith Saltman of the
University of British Columbia, Evans' work as a printer of children's picture-books is particularly notable; she believes he printed the "most memorable body of illustrated books for children" in the Victorian era, and the three illustrators, whose works he printed, can be regarded as the "founders of the picture-book tradition in English and American children's books". In doing so, Evans hired
Walter Crane,
Kate Greenaway and Randolph Caldecott as illustrators, all of whom became successful because of Evans' "recognition, encouragement, and brilliant colour reproduction".
Walter Crane , and printed in 1878. In 1863, Evans employed
Walter Crane to illustrate covers for inexpensive novels sold in railroad stations called "yellow backs"—after their yellow covers. Crane illustrated the early books, printed by Evans,
This Is the House That Jack Built and
Sing a Song of Sixpence, in which the simple designs are presented without background ornamentation and printed only in red, blue and black. These commercially successful books established Crane as one of the most popular illustrators of children's books in England. The designs gradually became more elaborate, as Crane became
influenced by
Japanese prints. His interest in design details, such as furniture and clothing, are reflected in his illustrations. Crane was abroad from 1871 to 1873 while Evans continued to print his work. Evans received Crane's illustrations via post, photographed the image to the keyblock to be engraved, and then returned a proof to Crane for colouring. In 1878 Crane and Evans collaborated on ''The Baby's Opera'', a complex project with a dozen fully illustrated pages, and decorative borders on each of the 56 pages. Crane visited Evans at his home in Witley to design the book. Evans gave Crane a dummy book to design the layout of the entire volume. The first print run consisted of 10,000 copies, but Evans quickly added more as demand for the volume grew. Evans added more hues to the illustrations, with "light blues, yellows, and brick reds, delicately blended" replacing the brighter colours of earlier work. In 1880, Crane illustrated and Evans printed, ''The Baby's Bouquet: a Fresh Bunch of Old Rhymes and Tunes
, which went on to sell hundreds of thousands of copies. The book shows influences ranging from the Pre-Raphaelites, Japanese art to the incipient arts and crafts movement. Initially Evans hired Caldecott to draw illustrations for nursery rhyme books, beginning with another printing of The House that Jack Built'' in 1877. Evans proposed to fill each page with an illustration, which were "often little more than outlines" to avoid the blank pages which were customary in toy books of the period. Beginning in 1878 through 1885, Caldecott illustrated two books a year for Evans, and secured his reputation as an illustrator. The books were released for the Christmas season, when sales would be sufficient to warrant print runs as large as 100,000. Later, collected editions of four works reprinted in a single volume were published. Throughout the late 1870s, Evans and Caldecott collaborated on 17 books, considered Caldecott's best, and to have changed the "course of children's illustrated books". Ruari McLean explains in the introduction to Evans'
Reminiscences, that as late as the 1960s reprints of Caldecott's
The House that Jack Built were "astonishingly, still being printed from the plates made from the original wood-blocks engraved by Edmund Evans". Evans invited her to Witley, and as he explains: "I was at once fascinated by the originality of the drawings and the ideas of the verse, so I at once purchased them." Evans believed her illustrations to be commercially appealing and encouraged Routledge to publish the book. Of Greenaway's first collection of illustrations and
verse, Evans writes: (1885), engraved and printed by Evans. The girl's hat is a solid yellow against the green background created by colouring with blue and yellow. When
George Eliot saw Greenaway's drawings, while visiting the Evanses at their home, she "was much charmed by them", however, she refused Evans' request to write a children's story to be illustrated by Greenaway. Published in 1879, Evans produced 100,000 copies of
Under the Window (including French and German editions) which helped launch Greenaway's career as an author and illustrator of children's books. For
Under the Window, Evans paid Greenaway outright for her artwork, and
royalties up to one-third of proceeds, after the costs of printing; for subsequent books he paid half of the proceeds after deducting the printing costs. Evans photographed Greenaway's drawings to wood, engraved in facsimile, and created colour blocks of red, blue, yellow and flesh tint. Evans paid particular attention to detail in the printing of her
Mother Goose. The "antique look" added to the
Regency style artwork, while his ink and colouring choices conveyed the look of a hand-coloured book suitable for a mass-market edition. To achieve the antique look, rough paper was pressed and printed, with the roughness restored after printing by dipping the paper in water. As an example of 19th-century book production,
Mother Goose is considered exceptional, and facsimiles were printed well into the mid-20th century. as well as
Mother Goose (1881),
The Language of Flowers (1884),
Marigold Garden (1885),
The Pied Piper of Hamelin (1887), and
King Pepito (1889). Greenaway benefitted from her association with Evans. As the leading publisher of children's books, Routledge provided Greenaway with a commercial base she may not have achieved without Evans' influence. Children's literature scholar Anne Lundin claims the distinctive quality of Evans' printing, as wells as his popularity as a children's book printer, linked Greenaway's name with his, thereby increasing her commercial appeal. During her career as an illustrator, Greenaway used Evans as sole engraver and printer. ==Later work and retirement==
