Hank Prussing's mural "The Spirit of East Harlem," a "towering homage to the neighborhood as it was in the 1970s," was based on photographs of local characters taken by the artist. "Everybody in that mural was recognizable," asserted Mr. Prussing.
Regarding the the fellow whose backside is shown below, putting a name to a face is out of the question. For foodspotting purposes, however, it's enough to know that the figure was painted from life, albeit at one photographic remove. I don't recall ever seeing someone keep his hands free in just this manner. "Baguette" might be the least disquieting option.
