The picture below shows a larger view of this Old Unused Bangor Maine Airport Restaurant Advertising Cigarette Ash Tray. The ashtray is not dated but it is old. It is made of clear glass and it is reverse imprinted in red on the bottom. The ashtray pictures the restaurant building framed by what appears to be a chain. It is marked as follows:
PILOT'S GRILL BANGOR, MAINE
The ash tray measures about 4-1/8'' x 4-1/8'' x 7/8''. It appears to be in mint unused condition as pictured.
