Welll.....
I have collected Fleer Stickers for a long time.....If it has been determined that the total printed combinations are let's say 109, that's it. I have shuffled through 1000s of these stickers, the calcutated total usually matches the collection [including all possible variations]. Keep in mind, I have collected Fleer BB and FB stickers since the '60s through 90s. If anybody would like a calculated total for any given year...LMK or when I can, I will post all.
These stickers have variations galore, some very subtle, while others are really cool. Caught my eye. I wish I could remember the source or the author, but I wrote to him to get his book awhile back, and requested a copy of this then OP book, this guy was right on, when it came to numbers.
