This Coro 'Geissmann Screech Owl' 1938 is rhodium-plated base metal with black and red enameling and pave rhinestones, depicting a screech owl in the act of swooping down on its prey.
Robert Geissmann was of German origin, and lived in New York. He was probably a freelancer who occasionally worked for Cor and the jewelry sector. He was an inventive designer, with an extremely realistic style which he combined with a touch of irony giving his chosen subject matter an almost fantasy-like appearance and strongly defined expressivity. The barely hinted three-dimensionality of the subject is emphasize by its position and the material and colors used.
Dimensions: 2 5/8" x 2 1/2"
