Salvador Dali (1904-1989) was the pre-eminent Surrealist
painter.
Dali described his most famous and powerful work, The Persistence of Memory (1931), as being a "hand-painted dream photograph". This painting features melting watches, an image that is often interpreted to depict a world in which time has become distorted.
A search hasn't turned up any melting guitars in any of Dali's art. Carol Butler at the Salvador Dali Museum reports;
"The only instruments we know of that Dali painted in a soft configuration were a cello and a piano as in his "Daddy Longlegs of the Evening-Hope" of 1940 and "Three Young Surrealist Women Holding in their Arms the Skins of an Orchestra" of 1936. Don't recall any soft guitars."
