I saw a picture of a Phillips 66 pricer sign. It has the arms to attach to swing in a curb sign frame by the pumps or road. It has Sixty-Six on the top with 22 9/10 for a price and Flite-Fuel with the same 22 9/10 price and is double sided. However there is no option to change the prices as it is one piece and it is either a painted metal sign or porcelian sign. If the price of gas changed you had to get a new sign with a new price. Anyone seen a sign like this and are they painted or porcelain? This one looks NOS.
