2 Vintage MCM Gray Smokey Drinking Glasses/Bar Goblets/Bar Tumblers 5.25"

2 Vintage MCM Gray Smokey Drinking Glasses Bar Goblets/Bar Tumblers Glasses are a smokey gray color with an ombre effect as the bases are darker than the bowls Approximately 5.25" tall Seen them listed in other areas as Federal Glass or Libbey Glass, Unsure what brand these are. They are in good condition with no chips or cracks, however, one has a stain (see photos). It didn't come out with dawn dish soap and I was unsure what else to use. Sold as is.
