Mosaic inlay cuff by Zuni jeweler John Gordon Leak circa 1940's-50's. Leak is one of my favorite of the C.G Wallace artists, his inlay work is blocky/simplified and always set into jet~in knife wing, dragonfly and butterfly designs. The tomahawk hallmark is Little Joe Begay, it was common for Wallace to have the Zuni do the inlay and Navajo silversmiths do the setting. (I'm not sure when this hallmark began to appear-you can see it on a few pieces also in Toshio Sei's book)
~picked up in Arizona...more Zuni.
