I wish the photo was a little clearer, but to me, it's the 'in sealed cans' lettering at the bottom of the can that gives this one away...it's computer type, the font is called Avant Garde...the original lettering would have been hand-rendered and irregular in places...the Texaco Clean, Clear flange recently offered on eBay (and posted on Oldgas) had computer-generated type as well...

The rust stains running down from the grommets are a nice touch...

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