Old green and blue mismatched plates from Digoin, Salins, Moulin des Loups

Set of 4 pretty old digoin, salins, moulin des loups plates, mismatched by their shape, size, origin, decoration but matching by their colors in shades of blue and green. In some photos, they all appear in shades of blue, but in reality two are in shades of green (see photos on black background). Three are stamped underneath: digoin, moulin des loups and hamage, ec salins. They probably all date from the first half of the 20th century. One is a soup plate. All have small defects: chips, small chips, small scratches or stains, so the ideal would be to give them one more life as decorative plates to adorn a wall. The largest measures 24 cm in diameter, the smallest 22.5 cm in diameter.
