These are pretty large (about 1.5 x 2.5 ft.) and very heavy.
They appear to be made using the porcelain process on a metal sheet/plate.
They have holes built into the four corners so that it can be screwed into the wall.
I think they're from the late 60s or early 70s.
My guess is that they're not reproductions...
They would be good to hang in the garage but I don't have any available wall space!
