Query: Hooray! Finally, the ultimate guide to collecting yo-yos.

The guru of yo-yo collecting and writer of the collectors corner in Fiend Magazine, Lucky Meisenheimer, has made the long wait for his book worthwhile. Truly he has created the "bible" of yo-yo collecting. History, Yo-Yos, String Packs, Patches and Pins it's all there. Anyone serious about yo-yos should have this book whether they collect or not, but don't even think about calling yourself a collector if you don't have this book.
