Rare 1975 Calico Ghost Town Studio Pottery Signed Mugs Yellow Flowers "Lore"

Rare find from a Southern Ca estate sale. These are both in excellent condition with no chips, cracks, or crazing seen. I'm not sure what "Lore" means or stands for, but I'm sure it had some meaning at the time, or maybe even the name of the shop. The bottoms are engraved "Calico Ghost Town 1975" with an artist's signature or mark that I can't make out. They are each unique with slighly different patterns in the flowers. Cups are about 4" tall and hold 8oz comfortably. Cups will be double boxed for shipping.
