It's not just ads.
This giant-size Pete Alonso card was used at Citi Field as part of the starting lineup display at the top of the Jackie Robinson Rotunda behind home plate. Thing is, at the time this photo was taken (4/4/19, the Mets' home opener), Alonso didn't have a Topps card. He didn't get one until Series 2, and the image used on that card was not the one used here.
This is Pete Alonso's actual genuine real 2019 Topps card (#475).
