I know some signs are dated but this one looks to be later than 1929. It is from a station started in the 40's with some other great buys from the attic. Can anyone help with the date?

It should be dated on the lower corner, all others I have seen were.

THAT "G-29" IN THE 2ND PIC COULD BE A SILK SCREEN FORM NUMBER. IS THERE MORE SMALL PRINT AT THE BOTTOM EDGES OF THE SIGN?

Mine says G-31, I have seen all kinds of numbers on different signs with the largest being G-59.

I'm not able to check mine right now, but if memory serves me correctly mines is ?-57 a painted non-porcelain sign.
