Check out this 1993 SP card of Colorado Rockie catcher Joe Girardi wearing a name dag during the Rockies inaugural spring training.
If you turn the card over you will discover that "Bryn Smith jokingly distributed badges such as the one Girardi is wearing to all the Rockies in spring training."
Crap! It's a "badge", not a name tag. Not sure this counts for Name Tag Day.
Any other cards out there featuring name tags or badges?
