The picture choice is a little odd since almost everyone is facing away from teh camera. We see lots of sides and backs.
The picture is also different from the one used on the two earlier version of the 2019 schedule. The pictures on the other schedules give us a clear look at Contreras, Baez, Lester, and Bryant.
My schedule collection goes back to 1961, the year I was born. Take a look at 59 different editions of the Cubs schedule.
