Interesting question/card. According to this checklist on the Old Cardboard website:
http://www.oldcardboard.com/r/r327/r327list.asp
card #'s 85 through 108 should only be seen with blue print on the backs and have a 1936 copyright date. It seems like in the past I have seen one of the high numbers with a green back, but my memory bank may have taken an early withdrawal. Would be interested in what others have to chime in about this subject.
