1993-94 Stadium Club Basketball Forum

How can you tell if the card is a promo?

There are no notes, but based on the images we have, the Promos do not contain "Created By The Topps Company, Inc." on the back at the bottom under the "TSC `93-94" logo. As you can see here for Shaq [1,2] and here for Pippen [3,4]. Although, Pippen does have a different back image whereas Shaq does not.
