This Pepsi-Cola drinking glass has a winter scene image or it could be a Christmas time image, which is ether a painted on image or a stencil on image or both. Looking at the heavier part of the image, in the white or snow area, on one side of the glass between the Pepsi-Cola Logos, in the image there is a 1/8 of an inch of what looks like an overlap of the white or snow area of the image. This happen many times with stenciled on images. However, the tree’s green branch over the overlap area does not have an overlap seam. Images that are, painted on, they would not leave an overlap in most cases. It is a rare glass to find not a lot of them on the antique marketplace. As for the age of the glass is debatable some say it is in 1970s and others say it was made in 1980s. I could not verify a definite date period. I also could not fine the company that made the glass.  I also could not find out if it was a promotional glass or from a collectable series. The glass is in mint condition with no image fade, chips, cracks, or stain or water marks.
