This listing is for a vintage Big Top Peanut Butter glass mug.  They are made by Hazel Atlas.  I believe they are from the 1950's.  The mugs Song is Daisy Bell with a picture and word to the song.  The painting is green, with the song on the back.  It has a lady and man riding on a bicycle built for two.  Parts of the design are missing.  Not sure if it was washed off or never there.   The mug measures about 4 7/8 inches tall.  I will have another set of mugs available.  I also have 3 other mugs in this set.
