This auction has a nice selection of competition boomerangs. This includes 3 C/C composite MTAs. One is made by Jonas Romblad and two were made by Georgi Dimantchev. There are several Fast catch tribladers and a couple of Gel booms. The second group of boomerangs are sport boomerangs, but many can be used in competition events. The third group includes all Australian boomerangs. Most of these are from my personal collection and I have had them for 50 years. There are also several from Brother Brian Thomas including a signature boomerang from an Aussie event. The last group has several magazines and boomerang books. There is a nice copy of the hard cover book by Bernard Mason, a HC book by Hawes signed by both Lorin and Mary. The most valuable book may be an early French book with a scientific explanation on how boomerangs return. This book precedes the famous Hess book.
