I think the designs found on Acoma Pueblo (New Mexico Native) pottery are just about as good as it gets, bold and complex and and perfectly resolved, even on very small pots like this one, moving the eye all the way around. I believe this pot likely dates sometime 1960s-80s, with dark brown/near black painted decoration over white slip. 

2 7/8" t x 3" in diameter. One very small surface chip on the exterior, as pictured. Some spotting visible on the white, mostly on the interior of the pot. Signed Acoma N.M on underside.
