I just picked up this team issued post card of Hall of Famer Dave Niehaus from 1983. The Mariners used to issue these for every player and coach for autograph requests and player appearances. According to the Earliest Collectibles of Baseball Hall of Famers thread, they list the earliest known Niehaus item was from 1995 so this pre-dates it by 12 years.
Around 12 years ago, a card shop that specialized in odd ball Seattle Mariners memorabilia showed me an example of this postcard (unsigned) and said that he had never seen one before in all his years of collecting. Since then this is the only other one I have seen (always in the market for Mariner postcards that I don't have). I wish that it was not personalized to James and by looking at it close I don’t see any way of removing the personalization.
