Now granted, some might argue that designing a t-shirt for a social media night giveaway is a harmless competition for the most beloved sports dynasty in St. Louis. And we wouldn't really be against something like that (in theory) per se, unless we happened to read the small print:
c) grants to Sponsor, MLBAM and each of their respective designees the perpetual and unlimited right and license to use, license, edit, modify, duplicate and/or create derivative works from his/her Entry throughout the world and in perpetuity, including, but not limited to, the right for Sponsor and/or MLBAM, as applicable, to publish, display, broadcast, distribute, reproduce, perform, create derivative works from and otherwise use and exploit the Entry via the Internet or any other interactive media, in stadium, on television, in print and/or any other media currently existing and hereafter developed and without limitation and without payment of any compensation to the participant or his/her heirs and successors, (i) on its own or as part of any audiovisual or other production; (ii) to advertise any products, programming or services of the MLB Entities or for any other advertising, marketing, publicizing and promotional purposes and in any materials related thereto; and/or (iii) for any other purpose whatsoever; and (d) release in perpetuity the Released Parties from any claims, demands, losses and liabilities of any nature arising out of or in any way connected with the Entry, and the use thereof as permitted hereunder, including, but not limited to, claims of false endorsement or infringement of rights of publicity or privacy. Nothing herein will obligate the MLB Entities to make any use of any of the rights set forth herein.
Thanks but no thanks Cards, we're going to throw this one back.
