Les & Arthur Janetzki were senior citizens when they started making and throwing boomerangs in the 1960s. The Janetzki brothers continued with their hobby until their death nearly three decades later. Les & Arthur made very few fine art boomerangs and they never sold them. Instead, they were given away as gifts to other competitors at Aussie tournaments. Les constructed the boomerang. He made his own plywood by laminating packing box boards together. Les then shaped the airfoils and sanded the boomerang surface smooth. Next, Arthur would apply art to the boomerang. When they were finished, the final product was a beautiful piece of flying art. Janetzki boomerangs were legendary for their high performance in events such as Accuracy, Consecutive Catch and Australian Round. These boomerangs were so popular that they were nicknamed the "Rolls Royce" of the boomerang world. At Brother Brian Thomas' suggestion, they started painting the initials "RJR" on the underside of the elbows. "RR" represented "Rolls Royce" and "J" representing "Janetzki". These boomerangs are almost never sold. Prices almost always start near $100 for unpainted examples. Some of the finest art examples have sold for more than $1,000!

The "SKIPPY" boomerang is the most original and valuable of the Janetzki boomerang designs. This is an early example without "RJR" painted on the underside of the elbow. Instead, the word "Skippy" is painted at that location. The most intriguing feature of this particular Skippy is the pyrography art work depicting a kangaroo on the elbow and line art on the tips. Only a few Skippy boomerangs were made with this pyrography decoration. The pyrography boomerangs were made out of laminated boards that were hollowed out in the middle and internal weights were inserted before the boards before they were glued together. This is the only Janetzki boomerang that I have seen with pyrographic art, making this a very rare example indeed. A pair of crossed spears are painted on each blade. This boomerang has been used and it came out of the Janetzki's personal throw kit. The only noticeable damage is a scratch in the paint banding on the underside of the dingle arm which should have only a negligible impact on the boomerang's value.
