The T-shirt printing machines at American Marketing in Clifton Heights haven’t stopped since the former NL MVP was introduced at spring training in Clearwater, Florida, on Saturday as the new face of the Phillies’ franchise.

“I want to be on Broad Street on a freaking boat or whatever, a thing, a bus, whatever it is and have a trophy over my head,” Harper said Saturday.

Making this colorful T-shirt bearing Harper’s image is a precise process playing out by the minute at American Marketing.

“I’m excited. The lineup looks very good right now. You got an MVP guy like (Andrew) McCutchen that I think can really help lead Bryce Harper as he moves through his career. And you got young and exciting guys like Rhys Hoskins and Jean Segura and (J.T. Realmuto),” Christopher Mongiello said.

Thousands of shirts were printed Monday. In the meantime, the T-shirts will be available online on Amazon and at Foreman Mills stores throughout the Philadelphia area.
