Elihu Thomson. Engraved invitation to attend the National Academy of Sciences semi-centennial anniversary at the Smithsonian Institution, April 1913, "signed" by the Academy president, Ira Remsen.
10x8", heavy paper, with an old horizontal fold at the center. Thomson's name is written by hand, but I'm pretty sure that Ira Remsen's signature is printed.
This is an unusual piece of U.S. scientific ephemera. $100
