Why are so many T202 folded in the middle?

[1880nonsports]

Hassan and Mecca putting triple fold cards into packs wasn't a new idea at the time. Duke had a couple different issues of "triple folders" inserted into their product (although not "clam shell" configurations) in the 1880's and before that there were some produced and collected under the category of mechanical trade cards. I'm with Rhett and others that most likely saved in one form or the other. The idea that one was supposed to seperate the panels due to the balanced advertising elements - is interesting but I just don't get there. Had a part of the panel been required to redeem something - I might feel differently. I think the thought might have been to make something interesting that would open up when taking the card from the pack - making for a wonderful SURPRISE moment when looking inside.....
