All 15 ashtrays are glass with some famous casino names such as Golden Nugget, Stardust, Harolds Club, Tropicana, Riviera, Flamingo, Golden Gate, Fairmont, Sahara, Thunderbird, etc. Everyone at one time were taking the souvenirs but was getting pricey for casinos so they stopped putting them out years ago. Now there is no smoking so you won't be seeing these ever coming back. Smoking items and advertising are becoming a hot collectable. These are it! Different sizes, colors and shapes. All in good condition. What an unique decor for game room, man cave or collectors room.
