In 1956, Sanchez's solo watercolor exhibition at Peridot Gallery (New York NY) of figurative New York or Caribbean street scenes was reviewed favorably by Stuart Preston of
The New York Times. His 1956 solo show at El Lyceum (Havana, Cuba) led to his association with Galeria Cubana de Pintura y Escultura and group exhibitions in Venezuela and Columbia. Although Sanchez did not return to Cuba after 1960, he continued to exhibit in biennials throughout Central and South America. At this time solo exhibitions of his work were held in San Juan, Puerto Rico, and Madrid, Spain, as well as in Houston, New Orleans, and New York. At this time solo exhibitions of his work were held throughout Latin America at the Museo Bellas Artes (Caracas, Venezuela),
La Tertulia Museum (Cali, Colombia),
Museo de Arte de Ponce (Ponce, Puerto Rico), as well as the Center for Inter-American Relations (New York NY). By the late 1980s, he turned his attention to New York scenes and depicted Bronx bodegas, storefronts, and garages as solid blocks of color. Since his death, solo exhibitions of Sanchez's work were noted at the Bronx Museum in 2001; at Boston City Hall in 2009; and at Syracuse University Art Galleries in 2011. Exhibitions of his work were held in 2012 at Saint Joseph College (Hartford CA), and the University of Virginia's Fralin Museum of Art, as well as in 2013 at the University of Oregon's Museum of Art, the University of Michigan, Indiana University, and the
Museo de Arte de Ponce (Ponce, Puerto Rico). == Recognition and contribution ==
