This Original Clapperboard was used during filming of the HAPPY DAYS episode THE DUEL at Paramount Studios, stage 19 in 1979. 'A French fencing champion comes to stay with the Cunninghams, and offends many with his rude attitude. But when he insults America—and Joanie—Fonzie reveals that he is a "black belt" in fencing'.
It's part of my HAPPY DAYS memorabilia collection and I'm in the Guinness Worlds Records for the "Largest Collection of Happy Days Memorabilia".
