So much has been said about the 1989 Upper Deck set, iconic set, great rookie cards of Ken Griffey Jr., Randy Johnson, Gary Sheffield, Craig Biggio, Omar Vizquel. One of the first sets to put an emphasis on photography, a staple of UD's line for years to come. The set was not without errors however, as cards #1-100(or 2-101 depending on source) can be found with either a ® or a ™. I thought you would need a microscope to see them originally, but the circle on the ® makes it stand out very visibly.
This said, if you have #62, #81, or #85 ® version...just sayin'. I might needs them.
