Regardless, the latest was a pseudo-art show of propaganda posters of all kinds:
On July 4, 2007, the PROPAGANDA III art show opens in San Francisco.
There will be no curation and absolutely NO censorship of any sort. Expressed political viewpoints, be they left, right, or center, will be displayed side-by-side, both online AND in the real world.
PROPAGANDA III will tour the globe through 2008, with dozens of one day art shows worldwide - the current schedule includes stops throughout north america, south america, australia, asia, europe, and the middle east.
NO art will be sold at any of the shows, although copies of the posters will be available for sale directly through the websites of participating artists.
This is NOT a commercial art show, but rather a global celebration of free speech + untrammeled freedom of expression.
SFist chimes in two times.
The posters themselves were very cool, very inspiring, but I was hoping for more controversial/right-wing/communist/authoritarian/uncle-sam-type stuff - instead, it was mostly lefty fare. Nonetheless, cool.
But the scene - the spot - the Phoenix Hotel and connected lounge - what a great spot. This is kinda what it looked like today.

Beers, bbq, rockin art, dj with turntables - what a scene.
I'm also on the mailing list for the Center for the Study of Political Graphics, where all these posters will live when this current art tour finishes. I first heard about CSPG when I was looking for some seemingly-rare Black Panther posters.
