Here is a little nugget of information that came directly from Upper Deck Awards website, which promptly redirected you to the MLB Properties vs. Upper Deck US District Court documents.
"Over the past decade, MLBP's revenue from baseball card licensing is well over $75 million."
"Upper Deck has negotiated at least six or seven trading card licenses with the MLBP in a 20 year period. The most recent license agreement between MLBP and Upper Deck granting the right to produce and distribute baseball cards in the United States became effective in 2006 and expired in October 31, 2009. The license had a two-month sell off period that concluded on December 31, 2009."
