John Higby (Mr. Yodel) made some of these collectors display shelves in 2000 and sold them at the American National yo-yo contest. I'm not certain of the quantity but there were not a lot made. These Collectors Display were 15" x 3.5" x 2.5" and made out of wood. Each display was hand painted by Higby. They were painted Red and Yellow with the date and designs of "Mr Yodel" on the outside and the inside shelf area was left Natural Wood.
