I found the carmine and blue 5 cent Beacon Airmail Scott's C11 attractive early in my stamp collecting. Later I would specialize in postal history with this stamp. I seek out covers from hotels, especially illustrated with images of the hotel on the front. I also like mixed frankings with foreign stamps, and interrupted (crash) covers.
Here's a Beacon Airmail on a burned crash cover. AAMC 29-7 Interrupted Flight Cover cancelled San Francisco March 9, 1929 1PM.
The plane, piloted by R.T. Freng - CAM 18 (Contract Air Mail) Boeing Air Transport from San Francisco to Chicago, crashed near Park City, Utah in a blinding snowstorm March 11, 1929. The pilot and passenger K.A. Kennecy escaped, the plane burned. 1,026 pounds of mail was salvaged, Beacon covers are not uncommon. It was forwarded from Salt Lake City with two different types of rubber stamped cachets.
