1988 unreleased baseball cards

This is my 1988 set of unreleased baseball cards. If you look close at the back of the package you'll notice a few names listed that were never in the 1988 set. These are players that were either traded or retired at the end of 1987.  Since the figures were cancelled we wound up with 9 extra cards since the cards have to be made in advance of packaging. These were not mass produced cards, but most pop up from time to time. It's unknown why, but the Goose Goosage is exceptionally rarer than the rest with  perhaps fewer than a dozen cards known
