Over the years, there was also a great deal of resistance from other companies. In 1967, Topps faced an attempt to undermine its position from the Major League Baseball Players Association, the League's nascent players' union. Struggling to raise funds, the MLBPA discovered that it could generate significant income by pooling the publicity rights of its members and offering companies a group license to use their images on various products. After initially putting players on Coca-Cola bottlecaps, the union concluded that the Topps contracts did not pay players adequately for their rights.
