Yeah, I originally had this posted this morning as Push & Ayer – Sorry. It looked like a Retna piece, but I saw the Ayer in there and thought that must have been the signer. Wrong. Pictures remain the same, though.
Shelley Leopold pointed out to me that the “Ayer” here is a callout. Ayer was killed several years ago. This thread contains pictures of some of Ayer's work and info about him. Many of the picture links are no longer valid though.
