This vintage Mack Truck Bulldog Chrome Cigar Ash Tray is a unique collectible crafted by Central Die Casting & Mfg, Co., Chicago, IL, USA.  The bulldog is a silver color.  Diameter is 7 inches; height is approximately 5 inches; weight is 1 pound 13 ounces.  I am the second owner, but it appears that it has never been used as an ash tray.  Excellent, pre-owned condition.  The design patent #87931 can be seen on the bulldog's chest.  A great addition to a collection or gift for any one interested in Mack Trucks.
