I've got a "40 Year Old Virgin" cabinet at home filled with G.I. Joe and Transformers, and a little bit of comic art on the walls, but only so much one can do with a tiny NYC apartment. Here are some photos of Metropolis' stash - as well as some specs for anyone looking for the same type of shelving.

FYI - There are 160 relatively new listings on ComicConnect.com, including many early GA DCs - particularly DETECTIVE and BATMAN.
