If you look closely at the bottom of the Esso Extra plate, you will see the Humble oval...the ad glass on the middle pump is Humble...Humble used two pump signs (Humble and Esso Extra), and there are two variations of each...


Looking for better Gulf items: signs, globes, cans and paper - especially porcelain Gulf flanges, and Gulf A-38 & A-62 ad glass...
