agree that it is stag and holly and not carnival glass. the Cobalt Color is off for that era. pictures of the bottom/feet would help with determining it's use. am referencing the ( bible of ) 8TH edition carnival glass, by Bill Edwards and Mike Carwile. the glass molds are still out there and being used. this might have been a later run made by fenton or whoever has the molds. find a fenton group, they might know more.
hope this helps 🙂
