Yes, It's whats called ROG or Reverse on Glass. I've had a few ROG but none like this one. This one is very thick, 3/8 of a inch, almost 1/2 inch. Has beveled edges. Possibly only one known to exist. Extremely Rare. LEON.
It would be very hard to top that. Unless I find a unknown Biewers Brewery ROG Sign or anything from William Miller Brewery in Mt Clemens. One of these bottles pictured below would be a nice find. LEON.
