What an adorable cobalt blue glass Nursery rhymes children's mug! Over the years there have been many iterations of this design. For instance there was one version that came out in the seventies that was shimmering blue carnival glass. This one is a bit older and we place its age in the fifties. There are several nursery rhymes represented on the eight panel's; Puss in Boots, Cinderella, Jack Be Nimble, Little Bo Peep, Hey Diddle Diddle's Cow jumping over the Moon, Little Boy Blue, Little Miss Muffet, and Ride a Cock Horse. In addition, the handle is a beautiful rendition of an elephant's head ears and trunk, Possibly Dumbo? The entire presentation is as we said; adorable! This cobalt blue glass mug is in perfect condition.
