EWR is the three-letter international airport abbreviation for Newark, NJ. Being a member of Continental Airlines' frequent flyer program myself, I recognize the font the "EWR" is in as coming from one of their junk mailings, most likely promoting that airport since they have a terminal and a hub there. I don't know why Seinfeld -- or anyone else-- would have it on his refrigerator.
