This left handed traditional art boomerang was made out of 8 mm Australian plywood and painted with Aboriginal style art in the 1970s. I purchased it from Rob Croll in 1985. The technique used by Lin Onus was to paint the boomerang with a base coat of red ochre. After the first coat was dry, Lin added a coat of dark brown and while the outer coat was wet, he etched the designs into the surface. The unusual pattern on the tips was done using a simple hair comb! Nice technique and it looks great. The airfoil on the upper surface is neutral. Handedness was made by putting an underside on the lower surface leading edge. This boomerang has undercutting for both left and right handed boomerangs, but the undercut bias for left handedness is greater. It is in very nice condition. A very rare boomerang by this famous Aboriginal artist who is also the son of the famous boomerang maker - Bill Onus. In the 1980s, I saw Lin Onus art selling in the major art auctions for $10,000 - $40,000, so this boomerang is offered at a very deep discount. Lin Onus died in 1996. Please view the photos below.
