This is “VMail“. To save airplane space, the letters were photographed and the film was shipped back to the US, where they were printed and mailed.

Hello Folks,
I hope this turns out to be a successful experiment. As I haven’t got any black ink yet I hope a pencil will do. Also I have been carrying this Vmail form in my pocket for some time so if your copy is sort of messy looking you’ll know why.
I am happy to tell you that the latter part of my boat ride was more enjoyable than the few days just preceding it. In fact under different circumstances, I might have enjoyed boat riding for a few more days. Solid ground did feel good though.
These last few days certainly have added to my travel experiences. I have now tread on soil outside of our good old U.S. You needn’t even consider where I would rather be though.
I am very happy that it was possible for me to see what little part of the scenery here that I did. The little sight-seeing that I had a chance to do was really a thrilling experience for me. All that I have seen in pictures can be seen first hand. It’s a real education. I am doing OK. Lots of Love,
Donald
