This reproduction advertisement postcard for Alfa Romeo features stamps of the Flinstone's Fred and Barney.
The user also carefully included stamps fro a few other places that she got at work. From left to right the stamps are from Saint Vincent and the Grenadines, the United Kingdom, and Vietnam. I've not gotten a postcard from either Saint Vincent or Vietnam. Saint Vincent has only sent 20 official postcrossing cards while Vietnam has sent just over 400 at the typing of this blog entry in early 2015, so my chance of getting an official card from either location is fairly low!.
