This is a very nice ashtray. It looks to be made of some type of composition material as on the bottom of it it does have some light cracking and crazing and wood doesn't typically do that. Overall, this piece measures approximately 5 in wide with the extended area and then 4.5 in in diameter around. Please see all photos. It's in very good condition for its age. If you have any questions please ask. Happy bidding and good luck!
