First of all, 22 of these 40 numbers have never been worn by any Cub. The unspoiled are 65, 69, 73, 75, 78, 79, 80, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 95, 97, and 98.
Next, there are four numbers (70, 74, 77, and 81) that have only been used by managers or coaches. Since they rarely if ever get cards, I'm going to limit the Frankenset to players. I'll have to go back and take out #2 Leo Durocher. He'll be replaced by Ryan Theriot.
Moving on, another seven numbers have been worn so infrequently that I haven't found a card for a player that shows the number. I checked ebay and COMC, looking at cards not yet in my collection but came up empty. I suppose I could make fake cards using pictures from the internet, but that seems like cheating. Instead, I now have a quest... find players on cards with these numbers:
61: Babe Phelps(1933-34),
66: Rafael Dolis (2011)
67: Tsuyoshi Wada (2014)
71: Gonzalez Germen (2015)
94: Felix Heredia(2001)
96: Bill Voiselle (1950),
All I'm left with are seven numbers between 60 and 99. And even some of the cards I'm using aren't very good. Desperate times call for desperate measures. Some have just a part of the number showing. Soler's #68 in on an unlicensed card. The logos are gone but the number is visible.
For #72 I'm going with the number that is on his helmet. I also had to borrow a picture from COMC since that cards isn't in my collection (yet!). And the final number, 99, forced me to use the only horizontal card in the set, plus I had to use Todd Hundley!
Here's what I've got from #60 - 99
