apartment therapy changing the world, one room at a time

Last week there was an article showing a "Behind the Scenes" of another design blogger, and there was a poster "For like ever" that I liked. Then a couple commenters talked about being sick of it, where I thought it was unique.
Does anyone have advice on where to find nice, funky screenprint posters that have a nice design aesthetic? I tried eBay but it was hard to wade through thousands of items, most of which were nothing like what I was looking for.

Thanks in advance for your help!

I don't know if they're screen printed, but they're beautiful...

Those are beautiful, but at 12x18" they're a little small....I could do a collection of three of them or something. I'm looking to have something interesting on a bare wall in my home office (it's a small room...one wall has a window, one is a sliding-door closet, and the other wall is covered by part of the desk and a bookshelf)

they have a classifieds section where artists sell posters (mostly hand silkscreened) for rock concerts, and sometimes prints not associated with a concert (ie. art). or browse around the site, find a designer you like, then link to their own site. they often have other things for sale on their own site. for example, check out:

speaking of posters -- i'm new to the area and just bought one of those robin rosenthal baby bird counting posters http://www.robin-rosenthal.com/poster.html#). can anyone recommend a frame shop? (we live in pac heights.) it's just a poster, so i don't want to spend a fortune, but i'd like it to be cute (for a nursery).

also, should i be making any special considerations for earthquakes? i'm not hanging it over the crib or anything, but should i be looking a plexi rather than glass or anything?

thanks!!
