The New York Central Lines 20th Century Limited tin sign has all the specs of the locomotive & a great picture of the engine.

 
Metal measures 10" x 12", with rounded corners and an 1/8" hole punched in each corner. Metal is .025 gauge aluminum.
 
Brand new, still in plastic protective wrap. A MUST FOR RAILROAD ENTHUSIASTS.
