There are no sites or other books that I am aware of about ashtrays. I always wanted to list mine but never did. I have about 100 different ones. The thing I like about ashtrays is to hunt them down and buy the at the right price. If I wanted I could pay big bucks on e bay, but I think that takes the fun out of it. Till recently this ashtray was the most I paid for one at 7 bucks. Have to love that. Barry
