The back,just as found 40 years ago.
Tankar--were you referring to this sign when you said "junk"? Just wondered as it is an original and no doubt it had grommets originally.
Thank you! The back of mine is the same as yours minus the red paint. The back of mine doesn't have any rack marks (the straight narrow lines you see across the backs of a lot of porceline signs) I was worried that may indicate it is a repro. However, again mine is identical to yours front and back (just a different batch number/IR year and without the red paint on the back).
