VTG American Primitive Magnets 2‎ Pc Fall Summer House River Horse Collectible

Vintage American Primitive Magnets Set of 2 Set of 2 round magnets featuring American Primitive scenes. One depicts Fall and the other, Summer. They are made of stoneware, possibly? I'm not sure. They measure just over 1.5" in diameter and are .25" thick. The edges and back are a bit rough looking but I think they are supposed to be like that . Gently used condition with no flaws that I can see.
