Vintage photo: Tobacco Delivery out of Honduras / Nicaragua ? *

* One of several photos bought at a local Wyoming [U.S.] auction. Some images were owned by, or taken by, a retired SD/WY crop dusting pilot who did travel to Central America, Cuba, Venezuela, and eventually Brazil. However, I have no way of knowing if he took these images. The quality is quite poor, and some or all might be "photographs of photographs" (2nd generation -or more- copies). The limited caption came from a small scrap of paper clipped to the back of the image - and it may or may not be accurate.
