This is my first ever post!
Warm regards from Essex, England. I’ve just returned to England from France with two signs that have been in my family for nearly 40years - A Mobil Pegasus (Perspex see other thread and a McColl Frontenac).
I am currently doing some research. This is a 72 inch , double sided sign. I would say the sign is in pretty good condition. One side needs a clean and I will attempt this with some very fine (0000) steel wool and Rottenstone powder.
Unfortunately, I can’t see any visible stamp/year. Question was it common for these signs to be stamped? How else can I track down its history or validate its authenticity? I’m pretty sure this is genuine. My father had originally imported it from the US.
Would welcome any guidance.
