Signed Rebajes Famous Gear Cufflinks !

Incredible Rare Rebajes Vintage Modernist Signed Copper Gear Machine Age Steampunk Cufflinks with movable gears. These famous cufflinks by Francisco ‘Frank’ Rebajes were featured on the cover of Copper Art Jewelry Book by Burkholz & Kaplan in 1992. Part of Renoir / Mattise Copper , many pieces went unsigned! The silver are tested and positive sterling silver. I cannot rule them out as anything other than an unsigned work of Frank Rebajes as they are virtually identical.
