Jon CanfieldPaul and others - while it has long been rumored AB's were smaller left to right because of pack size, this is, without a doubt, untrue. AB 10-count slide and shell packs are identical in size to that of Sweet Caporal, Piedmont, Sovereign, etc.
Now, this does not mean AB's are not "thinner" than other T206's. I think this is clearly the case (and not the result of trimming). However, I can confirm that it does not have to do with the packaging. Rather, it seems more likely that the American Lithograph Company cut the AB cards thinner for whatever reason. Maybe it was a mistake, maybe it was intentional - who knows. Point is, however, that the reasons for this was not due to pack size.
