This is an early 20th century example, possibly created for the art market or at least purchased soon after it was made, judging by its excellent condition.  It is likely pre-1920 as later examples would generally have a less generously formed  bowl, probably nothing more than a changing aesthetic.

This example is lovely with a relatively high and wide mid-body.  It is slipped and polished about halfway down, a feature generally associated with San Juan origin (and perhaps it is); it simply has more of a Santa Clara form in my mind due to the roundness of the bowl and lack of any kind of flattening at the shoulder.

Condition is excellent and unrestored.
