Dutch Clipper 12-Back Stormtrooper: Clipper had the license to sell Star Wars action figure toys in Holland during the late-70s. As you can see, the front of their version of the 12-back blister card features a nifty Clipper Toys logo.

The back bears text in both English and French, including the spiffy "La Guerre Des Etoiles" logo.

Clipper 12-backs are quite rare, even in Europe.
