I just won it at auction. There was no indication as to the size of the card, although by the looks of it I would assume it is similar in size to a T206. Am trying to get info on whether the back is blank or not. The auction house did not specify nor did they scan the back, so I am under the assumption that it is blank backed, but have asked for details. I purchased it more for the autograph than anything else. Any help would be appreciated!
