Set of Late 19th Century Songeware Soup Bowls

This is a late 19th century spongeware or potato stamped set of four soup bowls with rims, approx 10 1/4" [26cm] diameter, with hand-painted decoration in red-brown green and blue, with sponge or spud flowers in purple. 
 
Overall they're in good condition for spongeware, they're fairly uniformly crazed, there are odd small glaze flakes, but two of them have cracks, as photos
