I think they date back to the 1950's or so but not sure of that. They are guaranteed to be original and were produced by the Gorbutt Bowman Pottery Company that operated out of Belleville, Kansas. They stand about 3 1/8 tall and are in GREAT shape--NO chips, cracks or crazing.
One of them is marked "KANSAS" on the bottom. Add these cuties to your Jayhawk collection. The item "RARE HTF vintage Gorbutt Bowman Pottery KU Kansas Jayhawk salt & pepper shakers" is in sale since Sunday, July 7, 2019.
