1960 Topps Orange/Red Back?
 

Hi-

I recently acquired the 1960 Topps Woody Held card with a red/orange color back. Has anyone seen a similar one? Is it from a chemical reaction or something like that? I do not think it is hand colored but maybe it is. It came with a bunch of other 1960 Topps cards and none looked similar. I can take better scans if needed.
