Most philographers (autograph collectors) who collect the autographs of the Wright Brothers know that there were more than just Orville (1871-1948) and Wilbur (1867-1912). Reuchlin Wright (1861-1920) and Lorin Wright (1862-1939) were Wilbur and Orville's older brothers. There was even a sister, Katharine Wright (1874-1929).

In "The Sanders Autograph Price Guide 7th edition" published in 2009 (I co-wrote Chapter 1 "Authentication"), a bank check signed by Orville is valued at $500-$700. One signed by Wilbur is listed at $1930-$2795. The values depended upon how the check was signed. A bank cancellation hole almost always obliterates part of the signature on early Wright checks. The signature of the payee if endorsed on verso may also increase the value. For example, a check payable to and endorsed by Charles E. Taylor (1868-1956), the builder of the Wright Flyer's engine, is especially desirable.

and by Wilbur "Wright Cycle Co./ww." At times, Wilbur's "W" resembled Orville's "W."
