The Jets they used on the back of the fly boys shirt are Korean war era. FAIL. Love the CAN"T WAIT shirt tho.
I've got one out on CafePress also. A lot more simplistic. I'm not sure what the restrictions are on using the Jets team name. That one made by ZeusArts is pretty solid though.
IDK about the "Flight Boys" tees, but those "Cant Wait" tees are a sham, if your going to buy one why not get the official Bart scott "Cant Wait" t-shirt for $24. Also all of the proceeds go to Eric Legrande the paralyzed kid from rutgers. I know which one im buying
