These I think would be great sitting on the same shelf as the chunky pottery vase I just listed, though of course with a bunch of art and architecture books sandwiched in between! These are true period brutalist I believe, and I like that they look like miniature skate ramps too. Heavy and useful and feeling as if decommissioned from the MIT library!
6" t x 5 1/16" w x 4" d each. Good condition, with some wear around the edges and some darkening to the concrete.
