Upon reading this thread and thumbing through an old box, I found these in 10 minutes time: Neither of the Baines cards have the TM by the AL logo and it seems that all that are missing the TM logo are AL cards.
I found this on the McGwire All Star card: Extra splatter up by the name. One speck looks like dust on the print die. I have three of these so far and they are all the same.
I wouldn't consider that a true variation. Same card, just with black plate misaligned a little on the print.
The TM is factory set only. You will not find them in any packs. all the cards in the factory sets have TM.
So any idea which Murphy is the factory splatter and which is the wax splatter?
