YUENGLING'S ICE CREAM PENNSYLVANIA'S FINEST Back Painted Glass Sign Vintage

Vintage Back Painted Glass YUENGLING'S ICE CREAM PENNSYLVANIA'S FINEST Pa. This sign is in excellent condition. As pointed out in the pics there is some type of small particles under the glass that could possibly be cleaned. That backing/matting appears to be some type of white backboard/cardboard.

I haven't removed the back so not totally certain. UPDATE: I took the matting off to take some additional pics that are now posted to the listing. As you can see the graphics are painted on the glass.

The matting is only a piece of cardboard white on one side. Most of the particles that were under the glass were removed. NOTE: I have no idea of the actual age.

I searched all over the internet and haven't found another online.
