It aint much but its what I got; a reprint of a New York Central Poster and my railroad tin-sign collection (still growing). The big tins are reissues from recent years, but the small ones are Vintage Post Cereal tins from 1954 and 1955. They're hanging under my loft while the poster has been framed and hung in another part of my room.
And yes, we do plan on replacing the ugly push-pins soon with something smaller and less protruding, we're just having trouble finding small enough nails that can fit those tiny holes.
