Printing error, back misprint. Seeing as it is only the back that is shifted it is a misprinting not a miscut. Catalog it in your collection as if it were a regular copy of that particular card and move on. Maybe make a mental note to find an upgraded copy sometime.
I collect: Baseball, Football, Hockey, Mostly Vintage pre1980, My Homie teams - Washington/Baltimore Teams Senators (Twins, Rangers), Expos/Nationals, Redskins, Capitals, Bullets/Wizards - HOFers - Non-sport (mostly TV shows and movies).
My Trade List is very much a work in progress
