rustic hand-painted pottery bowls w/ big flowers, vintage Italy? old Mexico?

Assorted vintage handpainted pottery bowls, none signed, or marked with country of origin. We aren't sure if these are Italian pottery, or maybe Mexican pottery, or possibly from Spain?

There are four bowls 7" in diameter with the plain edge, and two bowls 6" in diameter with the scalloped border. All have some glaze crazing, none of the bowls have chips or cracks.
