The gold letters have a little depth to them and it looks like yet another material applied to the black canvas-type surface. Measures 16" x 9", overall. As can be seen, I did a quick rewire with an extension cord. I also bought a new bulb.
The only one I could find that was the correct size was 75w. It got real hot real quick.
I'm sure there's an appropriate bulb out there, with a little more looking. The item "Early 1900's Brass, Glass, Electric Lighted CASHIER Sign" is in sale since Tuesday, June 8, 2021. This item is in the category "Collectibles\Advertising\Merchandise & Memorabilia\Store Displays".
