1960's ceramic ashtray - promoting asbestos.

Unbelievable, isn't it? Combining asbestos and smoking. I was attracted to it purely from the history of asbestos and its weathered look. The telephone numbers date it mid to late 60's, it's difficult to nail a specific date, but from the look of it, it sure has had a hard life.
Despite its dubious heritage, it's still an interesting ashtray to own.
