I have come across this AC Sparky Flange. I have been told that this sign is reproduced and faked quite a bit so I wanted to get others opinions on it.
It seems to measure to what the one that sold for 2,000 measured at Mathews Auctions and it is stamped. The measurement is 15x10.75 inches. I've tried to do prior research on this sign, and from it I do believe that this is a real sign, but I would like to hear opinions because it is so highly reproduced/faked.
