Artist proofs are the test pulls printmakers make before a final edition — slightly variable, sometimes signed, often the most interesting version of a print. GAW is a working community print studio, not a commercial gallery, so what's on the table here tends to be honest studio work: etchings, lithographs, screenprints, the kind of thing that doesn't show up on Artsy. If you've ever wanted a real print and didn't know where to start, this is a low-pressure place to learn what you're looking at.

Practical note: the parking situation on Turk is grim. BART is the call. If you drive, the Civic Center Garage on McAllister is your least bad option.

With two hours, I'd get there early when the flat files are fullest, ask whoever's staffing which proofs are from the current residency cycle, and leave with one thing.
