The 1998 San Antonio Spurs 25th Anniversary Team set is a 27 card basketball set, comprised of the top 25 San Antonio Spurs (as selected by the Express-News) from the franchise's first 25 years. Packs with 4 cards were gummed to the inside of Sprite 12-pack cans that were sold only at San Antonio area Diamond Shamrock convenience stores. An exceptionally lucky fan could complete the set with the purchase of nine 12-packs of Sprite cans, since one of the cards in the pack was ALWAYS a checklist.
This is a team issued set. The copyright is "1998 San Antonio Spurs", not one of the big card companies. Complete sets exist and were give-a-ways at the annual Spurs dinner in 1998.
This set is considerably more challenging to complete than other local Spurs sets. The cards are rarely seen on Ebay and slipped under the radar of most Spurs fans, possibly due to the requirement to purchase large quantites of the official drink of the NBA only at Diamond Shamrock. The Sprite at area grocery stores (HEB, Albertson's, etc) did not contain the cards.
I suspect short printed cards since I opened 25-30 packs and had 7 Sean Elliott and 0 Mark Olberding. WOW, my family drank .
