Produced by Upper Deck, this 670 standard-size card set was distributed in two series of 320 and 350. Cards were issued in foil-wrapped 12-card packs and factory sets (of which contained five Gold Signature cards for a total of 675 cards). Basic card fronts feature color player action photos with white borders that are highlighted by vertical gray pinstripes. Subsets include Rookie Class (1-20), First Draft Picks (21-30), Top Performers (306-315), Up Close (631-640) and Future Foundation (641-650). Rookie Cards include Michael Jordan and Alex Rodriguez. A legitimate variation on the Alex Rodriguez card (#647) was verified several years after release. The standard card features the "A" from Alex on the card back text in grey/silver whereas the variation features his name in white. It's believed that the A-Rod "White A" variation is a significantly tougher card but exact estimates of it's scarcity are not known. In subsequent years other cards (such as Johnny Damon) were also verified to have this White Letter variation - thus it's generally believed that the entire Future Foundations subset was produced with white (and standard grey) letter variations.
