Neither the badge nor the decals were installed on my '66. They were included with the purchase of a close friend's new '68 who bought his car via the Program thru a U.S. Dealership in '67 or '68.
My car was also purchased thru a U.S. Dealership via the European Delivery Program in '66, but I don't know for sure if one of these decals came with its purchase or not. Regardless, I adhered one of them to my '66 for the fact that my car was purchased via the Program and therefore qualified it for one of these decals in my opinion and if someone noticed it at a show and inquired about it, I've got the original documentation to my car's purchase to back up the story, that's all.
