It's interesting, but the Hamburger Chili sign would have benefited from showing the mortar joints of the brick. In the black and white version it works much better without them. Maybe I'll try adding them in white pencil, if I'm feeling motivated.
[Since this was posted the Hamburger-Chili sign was removed. I assumed it was gone forever, but it has returned. It's been relocated from non-trendy Rogers Park to increasingly trendy Ukrainian Village/Wicker Park. Look for it on the north side of Division, west of Damen. I liked it better in Rogers Park. Even so, the neon has been repaired and the sign repainted.]
