Aviation Business Card (front and back):

During the 1915 fair, Allan Loughead took visitors on Bay Area flights. He and his brother Malcolm later changed their name to Lockheed (being tired of the constant mispronunciation of their Scottish/Irish name) -- and the rest is history.

Thanks to Thom Dickerson for sharing this card. Thom's father had a long history in aviation, including having worked with Lincoln Beachey -- the stunt aviator who tragically was killed at the PPIE while doing aeronautics in front of a large crowd.
