Arkansas Razorback Drinking Glasses

I got these Arkansas Razorback drinking glasses from a thrift store last week. I believe they are vintage. Does anyone know how old they are or who the maker was. I put a piece of black paper in one of the glasses so you could read the writing on them better. The razorback has a straight tail instead of the usual curled up tail and the spelling of "sooooeeee" is different from the "sooie" that is used now. They remind me of the vintage state souvenier glasses produced by Hazel Atlas. Any information would be appreciated!
