Kenner Canada 12-Back Header Card: Kenner Canada issued several header cards for their early Star Wars figure releases. Though, in general, they look very much like their U.S. counterparts, they turn up with less frequency and are physically different in several ways. Apart from the obvious presence of the French form of the logo, the most distinctive difference between the U.S. and Canadian header cards is in the thickness of their cardboard stocks. While the American variations were printed on thick, corrugated cardboard, the Canadian versions are rather flimsy, and thus are easily damaged. 21-Back versions of these Canadian headers were also issued, bearing both Star Wars and The Empire Strikes Back logos.
