German engineer, pilot, and rocket pioneer (1893-1933) who was killed as a result of burns suffered in an explosion at his rocket workshop. Flown rocket mail postcard depicting Tiling's post office rocket, carried on his breakthrough rocket mail flight of April 15, 1931, 5.5 x 3.75, signed on the reverse in fountain pen, "Reinhold Tiling." The postcard is numbered "136," of 188 flown postcards carried on this initial flight. The postcard bears an embossed photographer's stamp, "Rud. Lichtenberg, Osnabruck 1931." In fine condition. Tiling's demonstration that 188 postcards could be carried reliably on a rocket made his projects famous and drew widespread public interest. A scarce offering from this historic occasion.
