Gertenrich's are more common than the most common horizontal backed Witmor's (but not by too much), however, the majority of the Gertenrich's you will see have some paper loss on back. The Gertenrich's are a later issue and date from the same time as the E121 American Caramel Series of 120--ie outfielders will simply be O.F. and infielders are simply 3.B., etc. Most tougher backs from this series are from the time of the E121 "Series of 80" so the Gertenrich's are a little different in that regard. I haven't done any research on it or anything but I would imagine that that is a picture of Lou Gertenrich himself on back-- a former Major Leaguer around the turn of the century.Gertenrich cards...
