The conservation program application (in white) is from 1967, but the photo that was included in the application is from 1942. I also included the letter that detailed the program down below. As always, click on the images to see a larger version.
You’re right, that picture of the farm is confusing. Mostly because it is wrong. whoever cut the photo out of the larger picture just missed a few lines here and there. I added the actual outline of the farm to the picture. Then, for good measure, I did the same outline on a modern picture of the farm. Then, really just because I could, I superimposed the two pictures together, so you could see some changes.
