This weekend, June 2, 3, and 4, is going to be a pretty good one for rock-poster fans. First up is a show by Emek on June 2, opening from 6-8 p.m., at the Jupiter Gallery in Portland. Look for screenprinted gig posters for Radiohead, Pearl Jam, and the Foo Fighters, a number of artist prints, and plenty of pen-and-inks. The show runs through August 1. Then, on Saturday June 3, opening from 6-9 p.m., at Spoke Art in San Francisco, David Welker will be in town for an exhibition of drawings and prints (including the mini print shown above) entitled “Anthropomorphized Anomalies.” The show runs through June 24. Last but not least, on Sunday June 4, from 11 a.m. to 4 p.m., Chuck Sperry is hosting an open house and sale at his Oakland studio, where he will release a new screenprint called “All You Need Is Love,” display his Jerry Garcia prints, and have copies of “Helikon” and lots of other cool stuff available. One day only. See you there, there, and there!
