Remember these things?
Upper Deck had a lot of problems, too. And in the last couple years of its MLB licensing agreement, it inserted some massive sets into its packs. There was Yankee Stadium Legacy, and then the 20th Anniversary Retrospective. With 2500 cards, it's the largest set I'm trying to complete, and I've written about it several times. Because each card front is repeated on five cards, it's quite irritating - the five short blurbs on the back of the cards could have been combined into one card, and only a 500-card set could have been issued. But, then, Upper Deck wanted an insane set.
I've contemplated collecting 1/5th of the set - one card from each "series" - but regardless of how I do it collecting this set is really slow going.
At this point I don't know how many cards I have. I changed the format of my want list for the set so I don't have a count, though I am guessing I'm around 10-15%. The cards you see above came from The Baseball Card Snob, in exchange for some Japanese Yankees cards. If any of you have cards from this set you want to dump on me, I won't turn them down!
