Is anyone familiar with the German glassmaker Marke Faust? Or is that not a name but a trademark? Or...?
There are some excellent lego-like glass bricks embossed largely with that name, and I don't know anything about them. Probably 1920-1930s era. He's not mentioned in any of my reference books, and there's nothing online. He deserves to be better known. Check out the attached pic.
