Here's an interesting find I picked up recently: a printing block that depicts an early 1950 Schwinn lightweight. This appears to be the sort of block that could print a catalog or sales brochure. I'll need to find an ink pad to try it out. It looks pretty old and it should make a fun addition to post cards and Christmas cards I write.
Construction is a wood backer with the printing face being made of a waxy, hard rubber type material.
