Interesting card. The back is a "double strike", printed twice. Once with the correct Spahn back and once with the Bill Kennedy back. I'm guessing this never made it into a pack and was handcut from a discarded sheet kicked out during quality control check.
There is some paper loss on the front and back and a crease across the card, as shown in the images below.
I'm sorry, but I do not know how to price this. I cannot find any comps. I know in the T206 world, a freak like this would carry a significant premium on value. Rather than just stick it on eBay to determine the value, I would prefer it go to a collector here on Net54.
If you are interested, please reach out with an offer or to discuss. I prefer email at

If anyone has information about Bowman scraps like this, please feel free to share in this thread.
Thanks!
