One of our gallery tour stops was the Alex Klotz Gallery for a show of Andreas Feininger photographs. We realized we weren't on the mailing list, and therefore signed the gallery's address book.
Stephen Shore had signed in just before. We looked around, but have no idea what he looks like now. Might have been standing right next to us.
You know, the author of The Nature of Photographs -- also featured in a recent ICP exhibition.... That Stephen Shore.
