Dark Roasted Blend does some cool collections of photos, and they recently did a collection of science fiction space art originating mostly in eastern European countries.
This stuff epitomizes my favorite type of sci-fi. That wild-imagination, anything-is-possible kind of stuff. This collection shows that Americans weren’t the only ones with the dreams of space adventure. There are dozens of quality images there, if you’re into this kind of thing I strongly recommend you check it out.
