Sounds like this would be reasonable as 198 is 132 + 66. Sheet back then were 12 across and 11 high (132 cards). Generally, the companies would not leave all that paper blank, nor use it for another sport or non-sport issue (but I think they did a couple times earlier on), but they would pick certain cards to print again. This would certainly lead to double printing.
HOWEVER (yes, that's a BIG however)....
Say (for the sake of simplicity) cards 67-198 were on sheet #2, and 1-66 were double printed on sheet #1. They could have printed up 2x as many sheet #2s as they did sheet #1 and then there actually would be NO double prints.
So, what I'm saying here is there is a distinct possiblility that there were 66 DP cards, but we would need to know the layout of the cards on the sheets to know with certainty.
