Primarily Petroliana Shop Talk Forums Non-Petro Discussions Non-petro Discussion and Showcase Pepsi & Pete Sign Value and Authenticity?

I have this Pepsi & Pete sign and I've had it for a few years but have never been able to find another. Anyone know if this is an authentic sign and what it could be worth if it is?

I'm not sure if this sign was actually ever made, but I do know this tin embossed version has been selling for years and most aren't real.

A picture of the backside would be helpful and close up of the TM and mfg marking. Maybe one of the Pepsi experts can shed more light on it then.
