Getting back to the Maxwell piece at the top, it's one of those things I hate to see being sold as an original. I'm not sure who made these, or why for that matter, but they are from the 1970's and were some form of gas station premium. The more common ones being misrepresented are the Dusenberg, Stutz 8, Cord, Auburn, and other big names of the era. I have also seen "sets" that were several pieces glued to a cardboard backer. Each of these are bronzed white metal with soso quality and nothing on the back.
As for the real one shown, I do not have that style either, but if you want to see a collection of these search my profile for my images and you should be able to see them.
