Modernist handmade necklace signed "SAM W. GRAVES STERLING", c.1950's. It combines an art deco and Native American feel in an interesting geometric chevron design. Not certain, but I believe that Sam Graves was a contemporary of Frank Patania and H. Fred Skaggs, working in the southwest. This hollow silver necklace shows a high degree of craftsmanship. There are 3 sections connected by a paper clip chain. The middle section measures 2 1/4" by 1". Each side section measures 1 7/8" by 3/4". The depth of the 3 sections is 1/8" thick. The chain measures 11" long and the front sections measure 5 3/4" so the total is 16 3/4" around. Very unusual piece.....$8 for insured USA shipping plus applicable NY sales tax.
