Rare 1990 Topps #336 Ken Griffey, Jr. Not a true rookie card, but a highly sought after All-Star Rookie card. Of the late 80's early 90's "junk wax" era where cards were overproduced, this is one of the most sought after baseball cards, up there with the Frank Thomas error card. If you look at similar cards, you will see that the scrape on his arm is covered up/lightened.
This is a RARE card with errors where the scrape is a clear visible blood red color and the "attempted" cover up is not there. Instead the scrape is simply a little pixelated and there are small white pixels in nearby areas.
