This was my parents farm. I believe that your dates are off; this would have had to been 1972 or later. In 1970 we were milking 60 or more cows and there are none in the picture. We sold the cows in December of 1971. I am interested in buying a canvas wrapped image and digital file, what would that cost be?

I"m not affiliated with Vintage Aerial but, thought I'd answer your question because the site Administrator may not be reading all the comments. Digital File is $179, Canvas wrap starts at $179, more for the larger image. Should be able to see prices on the right hand side of the webpage.
Also, I do see 5 or 6 cows to the right of the large barn. I used the magnification feature which is available if you Login.

If it were in 1970 there would have been 100 head of Holsteins, 60 cows and balance in younger animals
