Thanks to the caption at the bottom of this photo, we know exactly when it was taken: 11am on Monday August 26, 1929. The Graf Zeppelin landed in Los Angeles on the final leg of its spectacular round-world 20-day voyage. Of interest to current-day Angelenos is that it landed at Mines Field, which had only recently been converted from fields of wheat, barley, and lima beans by realtor William W. Mines into into dirt landing strips. A year after this photo was taken, Mines Field opened as an LA airport and by 1949 it had taken on the name we now know it as Los Angeles International Airport.
