I bought this sign on my way home from Columbus Gas & was wondering if anybody has ever seen one..........it appears nos , has Stenpho Signs Dayton ohio stamped on the flange........its a 2 sided flange.....The paint is very thick & i can see screen marks, it has some spider webbing around white border of oval......when i first seen the sign i almost did not pick it up as i thought it was a reproduction & upon closer examination i'm 90% sure its old & from 20's or 30's.......i have never seen another & i'm wondering if anybody else has.......thanks
