These three slag glass marbleized ashtrays were made by the HouzeX Glass Co. in Point Marion, PA as late as the 1940's. They were after market car ashtrays attached to the dash with a rubber suction cup. The blue one still has the nickel insert and brass button to hold the rubber suction cup. Priced separately all are mint, left to right: light green, $45; dark green swirl, $65; dark blue with nickel insert, $80. Or all three for $170. Shipping add $10.
