Note that I am not able to identify the airplane in this great photo.
On the back of the card the pilot? and writer mentions the AT-17 plane, but that is not this one I'm sure. Will leave that to the professionals.

Situated over what looks to be fields and land, beautiful cloud formations behind the plane. Note the pilot appears to be looking at the cameraman.
I believe the tail numbers or serial numbers are what is referred to at the rear. R253.
Perhaps again someone with more knowledge can identify the plane, location or era through these numbers.

It is approximately 3 1/2"W X 5 1/2"L. 3/4's of the card is the photo.

Please examine photos carefully, both front and back. Postmarked Lemoore, Calif. 1943 November.
Sent by NC Donald Yolton Class 44B (1917 - 1982 La Crosse Wisc. - La Crescent, Minnesota) and sent to Pfc. Carl Zobel of Yuma AZ. (Sgt Carl Julius Zobel - 1920 Minneapolis MN - Germany 1944)

Sadly, he didn't make it home.

The above information is my belief and research on the sender and addressee. I'm hoping this info. is helpful historically and for genealogy purposes.

Please see and enlarge photos and email with any questions prior to purchase. Thanks
