Vtg B&W Aircraft Photo PORTERFIELD Trainer Lee Mansdorf LA CA Plane Broker For Sale

Interesting old black and white photo measuring just over 8x10. Stamped by Lee mansdorf on the front and rear with information on the back. He was an airplane broker and designer. I'm not sure when the photo was taken. I have several photos that appear to be of actual or types of planes he has for sale.

It's in fair condition with a few issues noticed with the gloss. When held sideways to a light multiple spots and swirling marks are noticed looking similar to rings on a tree. Not as noticeable when looking head on. Please see my photos for these details.
