These were the only illustrations in a huge textbook on the subject of potato farming.  I saved the key with the varieties named, and if you are interested just click on an image and you will be taken to my etsy shop where I have these prints along with the key for sale.  The varieties are Burbank, Green Mountain, Rural New Yorker, Early Rose, Early Ohio, Beauty of Hebron, Irish Cobbler, Triumph, Pearl, McCormick, White McCormick, Perfect Peachblow ( Red McClure), and Up-to-Date.  If you can match the name to the potato I’ll email you the images for free!
