While you can’t really help but notice this colorful wall at the entrance to the F Subway Line at Second Avenue and Houston Street, it takes a keen eye to spot the many street artist and taggers represented in this confined space. Aside from the large Skull and Demon Mural (not sure who the artist is, clues left in the comments are appreciated) displayed on the southern exposure of the Avalon Chemists building, we noticed the following:
Suckadelic Star Wars parody action figure: Gay Empire Homotrooper.
Update March 12, 2017
