I opened a case of these with the same 90521 date code.. And pulled several Griffey and Randy Johnson cards, but NO Billy Ripken cards at all.
So either my case had very odd collation, or this was a time period when Fleer had totally pulled the Ripken card from circulation (as we have heard did happen at some point). The L# in the title is just my inventory code. This item is in the category "Sports Mem, Cards & Fan Shop\Sports Trading Cards\Sealed Trading Card Boxes".
