It's clean. Safe color choice. This might be my favorite of the Jackson Robinson packaging.
It's going to be interesting to see how much Jackson actually knows about baseball by who he uses for the court cards. I always questioned his Federal 52 choices. The King should be someone who represents a King in his respective field or occupation. Sometimes there are clearly better choices.
As for fed King choices I set pretty clear boundaries to use only the most widely used and recognizable currency portraits. As most of them were Presidents I would categorize that as being the "king" in their field or profession. the Reserve Note courts were chosen based on my own personally attachment to the specific portrait.
As for the choices of the National Pastime Deck, it is focused specifically around the "Dead Ball" era and the court cards have already been chosen by the National Pastime Museum as they are who asked to collaborate with them in the first place and I am deferring to them for their knowledge and expertise for the players used.
