Awesome Maw Paw Pottery S&P Shakers Arizona Peyote

This is an awesome set of salt and pepper shakers in great condition. One shaker features an Indian woman and the other an Indian man. I don't know much about these shakers but was told these might have been made by the Peyote Church people and they might be the older version of Mana pottery. The bottoms are marked Maw Paw 78 Tucson AZ. The 78 might be the year but I think it is more the number of the pottery piece. These measure 4.5 inches tall.
