I have a fondness for artwork that evokes the simplicity and mass-reproduction aesthetics of WPA era travel posters and political wood block prints. Posters are often deceptively simple in their design, but the former-printmaker in me appreciates the challenge of creating subtlety using basic techniques and only a handful of colors. I like artwork that looks like it might have been made in someone's basement, and was intended to be posted on the city walls after midnight with cheap wheat paste. Stuff that might have adorned the walls of a travel bureau in an alternate timeline, gathering dust under a lazy ceiling fan.
I'm always prowling the web for examples of work like that. Somehow I came across Justseeds, an art collective in Pittsburg, and was blown away by the work there. Much of it is powerful, political, and actually affordable for normal people.
(Just to be clear, this is not a paid endorsement. I don't even know anyone at Justseeds, I just love what they're doing.)
Mazatl's stuff is just amazing. One of his themes is extinction. I find this image, in which a wolf tries to outrun its own destruction, utterly devastating. (This print is not yet available, but through his own site Mazatl said it soon will be.)
