This is a Mexican pot; don't remember exactly what province or what this style is called, but definitely Mexican, made of earthenware. The design seems very derivative of some Native American Pueblos, notably Acoma, Zia and Zuni but both the pottery and painting are cruder. The similarity is not surprising considering New Mexico (where most pueblos are) was once a part of Mexico. I have been collecting old Mexican pottery for over 20 years. There are many different types and styles that are associated with particular regions and periods. I have at least 3 pieces that are of this type. It's just a guess, but I would say this piece probably dates from the 1930's-40's.
