I recently picked up what I think is a 1917-20 M101-6 Felix Mendelsohn card of Jim Bagby. When I received the card I compared it to another FM card I have of Guy Morton and I immediately noticed the differences. The Bagby card is bigger than my Guy Morton, about 4-3/4" x 6-3/4" and it also has borders. I flipped through my Standard Catalog and checked out Old Cardboard and both sources say the set is borderless, like my Guy Morton. Although these references differ slightly on card size, neither shows anything as big as my Jim Bagby.

Are some FM cards bigger, and with borders? Is this something different?
