Juxtapoz - Juxtapoz mag is somewhat synonymous with the pop-surrealism style of art (at least according to Wikipedia), and created by painter Robert Williams
One thing that's nice about this mag is that subscribers get their own cover. One reason I might be subscribing any moment now.
Juxtapoz can be found at Magnation, and probably plenty of other places too.
Founded by two artists, Annie Owens and Attaboy, I've picked up a few editions of this. It's the magazine that opened my eyes up to a whole host of great artists and galleries.
They've also recently ran an exhibition, Bitters and Sweets at the
Outre sells this one.
Labelled the magazine for 'Asian and Asian-American pop culture and beyond', Giant Robot is another great way to discover great artists and other general, radom stuff.
Now I'm sure there's plenty more art magazines worth reading - these are just the one's that I've bought so far (excluding the art almanac). Anyone else have some suggestions?
