I recently acquired a vintage 1960 Playboy Crystal paperweights. Where can I find more info on this?
It has the playboy Log engraved on top, and come in Christies auction and one for sale. I want to know more about it, does anyone know Another way to find information?
Obvious answer: Send a letter to Playboy (no, not for publication, send it to the editor seeking information)
