Tim NewcombThe Old Cardboard graphic on M116 backs which was linked earlier in this thread has some flawed info:
Here's a quick clarification:
"When You Think of..." back:
appears in black in series 3 only, but it appears in blue in series 1-18
"If you want" back
Appears (in blue) in series 1-18, but not in series 19-24
"300 Subjects" back
Appears (in blue) on all Series 19-24 cards, with reasonable frequency on Series 1 cards, and on a few other series

Also, as Scott B. helped me to determine, the assignment of cards to series that Lew did in the article reprinted in this thread, while basically accurate, has a few errors in it. If you count you'll discover that one of the series has something like 16 names attached to it, another has only 8; and a few other problems.
