Brilliant and versatile Croatian-born American inventor and engineer (1856–1943) whose discoveries revolutionized the understanding and practical applications of electricity and magnetism. Unbelievably rare vintage glossy 8 x 10 head-and-shoulders portrait, signed vertically in fountain pen, “Nikola Tesla, Aug 13, 1934.” In very good condition, with scattered creases mainly to background and edges, heavier crease to lower left corner, some light areas of mild discoloration, and some red ink marks along right edge. Any autograph material from Tesla is quite scarce, even more so in signed images—this is the first we have offered in over 30 years. Pre-certified John Reznikoff/PSA/DNA and RR Auction COA.
