22-P-233

Regular price $20.00

Vintage original press photo, 8x10", b&w.  Lengthy press release on reverse shows Harris M. Hanshue (top), President of Western Air Express, and Dr. Harry Bateman, Dir of Aero-Dynamics at CalTech with some of the models used to increase aircraft speed.  The release also announces a grant from the Guggenheim Foundation.  Release date is 7/18/1927.  Very good.
