I've had this ash tray (guess) for 10 or 15 years and often wondered about it's origins. The bottom has a lot of wear, so I think it has some age to it. It looks a bit like some Blenko pieces I have seen in their older catalogs (late 60s, early 70s) but I'm not quite sold on that identification. Does anyone has a guess as to what country this was made in? Guessing it would be a stretch to identify a maker...
