This UAT Aeromaritime French Airlines ashtray with a DC-8 is the best of the four plane-related ashtrays I have. None of them is equipped with an actual model plane!
This one has a photo of a DC-8 with US registration on the wing. The decal is on the bottom of the ashtray. My mom asked management's permission, in 1980, that I may have it, when I spied it in the lobby of the Venice hotel in which we were staying. It has very little wear, and it is made of thick glass with decorated indented sides.
