Vintage pottery mugs Arizona Hopi Native American pair RARE collectible signed

Beautiful Arizona Hopi pottery mug pair. Probably circa late 1950s, early 60s. Both mugs are in great structural condition with no chips, cracks, breaks, or repairs. Crazing and staining is evident due to age/use/storage and both can clearly be seen in the photos. Mug with the pink measures approximately 3 3/4” high x 2 5/8” overall at the lip. The other mug measures approximately 3 7/8” high x 2 7/8” overall at the lip. One mug is signed, as shown in the photo. Artist is unknown but I believe both were done by the same artist. Feel free to ask any questions and don’t forget to bundle to save. We love reasonable offers!
