WIth Baseball, Topps has the exclusive license with MLB but not the MLBPA.
That first resulted in.. instead of 5+ manufacturers producing 20 sets a year, now Topps produces 20 sets a year. Often with the same pictures used.
Now the MLBPA has signed licenes with other manufacturers and even more sets are out there but without any logs or trademarks being allowed on the cards.
I would rather go back to multiple manufacturers having a license but telling them the amount of sets they can produce is limited, or they have to be truly unique from each other.
