What could be called the Far Outer Sunset Arts District is booming, thanks to painters/printmakers Annie Galvin and Eric Rewitzer, who recently moved their workspace and gallery, 3 Fish Studios, from Dogpatch to a storefront so close to Ocean Beach, you can smell the salt through the fog. Galvin’s popular 49 Mile Scenic Drive paintings are available here in postcard form, and Rewitzer’s haunting linocuts of iconic San Francisciana start at $20.
