4 Small Delft Shoes or Clogs

This is a set of 4 Delft shoes or clogs -well, 3 Delft and 1 Portuguese- decorated in blue on white. One is unmarked, 2 have markings that I can't completely decipher and the last is marked "Portugal;" the Portuguese shoe is the shoe with a pointed tip. The other 3 are decorated with windmills and there are no chips or cracks. The Portugal shoe does have crazing. For reference the Portuguese shoe is 4 1/4" long.
