While down in Cape May for Thanksgiving, I visited one of the many local antique shops and found a few T206 cards for sale including the below two cards.
I'm fairly certain the Orval Overall portrait has the orange (red?) wet sheet transferred from another Overall portrait.
However, for the Kroh above, I was a little confused. There is definitely a Piedmont back transferred on the front (most visible in the upper left hand corner). However, the back, which contains a tremendous amount of color is more confusing, though there is a face fairly clearly found on the upper right hand side of the card. I was wondering if anyone had any opinions as to which card appears to be on the back. My original thinking is that it was Kroh on front and back, but I was hoping some more informed opinions might be willing to weigh in here.
