This set was born off of a challenge on a Facebook group I belong to, in which we were challenged to recreate a set from the past that we loved and put it to a modern day element.  I chose the 1991 Score Football Hot Rookies subset.  I always loved this set, even though a lot of card collectors abhorred the pink and yellow design.  I put together a bunch of cards that represented rookies from the 2018 season in MLB.  I sent out 21 cards originally for signatures... we'll see what comes home.
