For any of you interested in old advertising printers blocks, I've got two listed on Ebay right now. I got frustrated trying to stamp them (they're a metal stamp mounted on wood) although someone on here said you have better luck if you put a thin sheet of foam underneath them when stamping. I haven't tried that yet, just decided not to bother with them. They're very nice for anyone who collects them or wants to get into antique stamping.

My user ID is c-girl on there. You can search under me as a seller.
