Photo # 21
Vintage photo, of a U.S. Mail biplane and
a U.S. Mail truck together. Nineteen twenty-six is painted between the
two wings on the tail. The crowd of people in the background of the photo
indicate it may have been taken at an air show.
Caption ID from Roy Nagl: K O Eckland at aerofiles.com believes that the photo may show a Lincoln-Standard LS-5. There is another photo of this aircraft on aerofiles.com, which he refered to.
