At the 1995 National Sports Collectors Convention held in St. Louis, Skybox debuted this Cal Ripken promo card to introcuce collectors to it's new baseball card line E-Motion. These were considered super-premium cards.
This card was identical to Ripkens card in the set with the exception of the "Promotional Sample" stamped in gold foil on the front and back of the card.
A brief history of Skybox International: it was originally formed as Impel Marketing in 1989. In 1990, the company was renamed SkyBox International. In 1995, Fleer acquired the company and produced cards under the Skybox name for several more years. When Fleer went bankrupt in 2005 the brands, rights and business strategies were purchased by Upper Deck. Then, as we all know, Topps screwed Upper Deck.
