Inusual Delft Blue Windmill 6" Tile with Boat pulled up on shore

Delft tile 6 15/16" x 6 15/16" Features a windmill, trees, a second windmill, and sailboats. In the foreground is a boat pulled up on the shore. I've never seen this on a Delft tile before MARKS: - back has a square shape in the center with incised horizontal lines - these lines are inset with three smooth (unlined) circles - one of the circles has numbers on it at the top, bottom and sides - the numbers are 24, 9, 1, 2 - in the center of the number circle are 4 rows of raised dots - the first three rows have 3 dots; the last row has two. CONDITION: Very good pre-owned condition with the caveat that upon close inspection I found one unobtrusive chip on the corner (see last 2,pictures, the last of which is magnified 5 times actual size). There may be some minor wear that you could expect of a pre-owned item. Questions? Leave a comment below!
