David Hockney
(1976)  
 

The Blue Guitar is a suite of twenty etchings with aquatint by David Hockney, drawn in 1976–77 and published in 1977 in London and New York by Petersburg Press. 

The frontispiece to the portfolio mentions Hockney's dual inspirations: 

"The Blue — Guitar — Etchings by — David Hockney — who was inspired — by — Wallace Stevens — who was inspired — by — Pablo Picasso"

In 1976 Henry Geldzahler introduced Hockney to Wallace Stevens' 1937 poem, The Man with the Blue Guitar, which used Picasso's Blue period painting The Old Guitarist (1903–04) as its central theme. Hockney produced a number of drawings in response to the poem, which highlights the problem of the imagination's role in interpreting reality, and produced a set of coloured etchings using the method devised by Aldo Crommelynck for Picasso to make colour prints. Hockney said his illustrations "like the poem, they are about transformations within art as well as the relation between reality and the imagination, so these are pictures within pictures and different styles of representation juxtaposed and reflected and dissolved within the same frame. Wallace Stevens (1879–1955) began writing poetry in his 40s, and, while never a popular poet, is counted one of North America's most influential poets of the 20th century."
