Yo-Yo fanatic

Florida doctor prizes playthings on a string. John "Doc Lucky" Meisenheimer always has a yo-yo in his pocket. With nearly 6,000 yo-yo's he has the largest collection in the world. He has floor to ceiling glass cases encircling the loft of his home library to house his collection. He also created a yo-yo headed manequin covered with 603 yoyo's. Some of his yo-yos are antiques including a circa 1790 brass toy from England, a few are rare, like a wooden prototype-one of only six known to exist-made around 1955 by Duncan Toy Co for Coca Cola. Others blow bulles, generate sparks, and emit scents.

He has a 6' tall, 820 pound yo-yo made in 1990 by a woodworking class in Jasonville, In. He spotted to toy on eBay and bid on it. He keeps it in a backyard shed.

When he was unable to find a definitive guidebook on the subject, he spent 4 years researching and writing Lucky's Collectors Guide to 20th Century Yo-Yo's. The love affair of yo-yo's began after marketing genius Donald F. Duncan Sr. hired salesmen to demonstrate yo-yo tricks across the country. He also partnered with William Randolph Hearst to sponsor yo-yo contests. For more information go to www.yo-yos.net.
