Inventors The Wright Brothers were pioneers in the aviation field. The younger of the two, Orville, signed this check issued by the Winters National Bank & Trust Co. in his hometown of Dayton, Ohio. The signature is in 9/10 black fountain ink and the check has a few fold lines but otherwise appears EX. Wilbur and Orville Wright built the world's first successful airplane and sustained the first human flight in 1903.
