Attention, collectors! Steve Sprague has put the word out that he has an original prop used by Doug Henning that is up for sale. It’s from the World of Magic 4 television special in 1978. The prop is a red curtain painted with a gold dragon, and two wooden dragons that hold it. It was constructed by Johnny Gaughan specifically for the trick, which saw Doug Henning trading places with celebrity guest Brooke Shields. 

You can see Sprague’s full description on the Doug Henning Project’s website, as well as instructions on how to purchase it for yourself if you’re so inclined. Or you can just see the trick in action in the video above.
