Ebbets Field Flannels Founder Jerry Cohen grew up fascinated with sports emblems and uniforms. As a youngster, he would purchase baseball cards to see the uniform changes and colours rather than for the players. Fast-forward to 1987, when he was trying to find a vintage flannel baseball jersey to wear onstage with his rock & roll band. Not satisfied with what was available, he became a bit obsessed, and eventually tracked down some old wool baseball flannel and had a few shirts made for himself.
