Ebbets Field Flannels EFF jacket like a work jacket with embroidered letters and cool logo patches. I think this is the groundskeeper jacket, it’s a lined canvas style work jacket. Super awesome just too small for me. Team is the Chicago Whales, from the short lived Federal League baseball. Also known as Chicago Feds. Back has Weegham Park which predated wrigley field. 19” across chest. Good used condition
