there are two variations of this sign- one with the circle R between the lower of the S & G & has reg US pat off below ethyl logo with, "with" above the logo-

last version is later example of same style pump sign with later ethyl logo -

what bothers me about yours is the yellow & orange doesn't look as bold - I do know that Bill Campbell/San Jose

reproduced some of the signal pump plates years ago & they were about dead on - possibly one of those

picture of other version & one of like sign of subject -

"quote sign of subject 12” and black on backside" .... sign should measure 11 7/8" and black on backside

sign of subject is questionable - please add your 2¢ .. ... cool
