The album cover art work was by artist
Ray Smith and was the first of three of his "paint socks" to feature on Henry Cow's albums. Smith had appeared with the band at several of their early 1970s concerts, performing a variety of activities, including
ironing, reading text and miming with
glove puppets. He suggested a woven sock on
Legends front cover, and insisted that the band's name should not appear there.
Chris Cutler said in a 2011 interview that Smith continued the theme on Henry Cow's next two albums, with the sock changing "to suit the temper of the music". In his book
Prog Rock FAQ, Will Romano wrote that
Legend "might [have] the most unusual and slightly amusing cover featuring a sock." Smith created it with a
pastry bag that he used to squeeze out long strips of
acrylic paint, which, once dry, he wove together to produce the sock. He explained that the sock has no connection to the music, "It's an independent object". Smith described the picture of the sock on the album cover as "clear, fresh and optimistic" which "suggest[s] something electrical". The other two Henry Cow album covers to feature Smith's "socks" are
Unrest (1974) and
In Praise of Learning (1975).
Legends "sock" also features on the 2006
Henry Cow Box cover. Smith produced a cover for Henry Cow's final album,
Western Culture, but it was not used. The design illustrated an industrial city viewed from above with the text "Henry Cow" appearing in its streets. ==CD reissues==
