That works out to just around thirty percent (30%) of the exhibition.
Just to get a sense of how representative a selection of Sakoguchi's Unauthorized History of Baseball series this exhibition is, we consulted Sakoguchi's web site, where 225 of the paintings are displayed (in somewhat smaller image sizes than we've had the good fortune to use here--our thanks to Jan Sakoguchi for providing them).

So for the entire series, the percentage of paintings with team pictures works out to just under thirteen percent (13%).
Does that mean that Terry Cannon (who selected the paintings to be featured in "Purpose Pitch" has some kind of penchant for team photos? While we can't completely rule that out, there's a more logical explanation available.
A sizable portion of the story that the Reliquary wanted to tell in the particular location (southern California) where this exhibit has been housed dealt with history pertinent to what residents sometimes call the "Southland." Much of that history, it turns out, was best conveyed via the team photos for local, non-professional leagues that flourished during the two decades prior to World War II.
Hence a much higher preponderance of paintings with team photos here than in the series as a whole.

Ben's work is thus a visual analogue to the ongoing efforts of the Baseball Reliquary. They go hand in hand, and in a perfect world, there would be a building in which all of those who own paintings in the Unauthorized History of Baseball series would donate those works to what would also be a gathering place for the programs, documents, and artifacts of the Baseball Reliquary.
While the Reliquary continues to explore the possibility of a permanent home for its collection, it's clear that a longer-term (albeit "utopian") solution along the lines of what's described above would be the optimal solution.

Let's start the ball rolling by finding a way for "Purpose Pitch" to be a traveling, national exhibition. Once that happens, the world of baseball (and the world at large) will realize what it really has on its hands with the Baseball Reliquary and its unique symbiosis with Ben Sakoguchi.
If we build it, they will know...and they will come.
