Add me to the list that really likes these 3 sets. I'm down to needing 1 each for E91B and E91C, and about 6 for E91A.
I feel a bit guilty about this now that it seems a few people are looking for Slagle in E91A, but I've got a few uncut strips and one of them has 4 Slagle's in it.
It's out getting framed right now and should be back on Friday, but here is the scan from the auction house showing the strip. It really doesn't seem like any are scarcer than any other.
I can't pull a bigger scan, but it's lot # 60 from the 10/09 Mile High auction. I picked up 2 strips in that auction, and know they had a bunch of them offered previously.
Slagle is #1,4,9 & 14 counting from left to right
