Collection of 4 vintage ceramic ducks

Beautiful recovery from Holland: collection of n. 4 ceramic ducks of different shape and size, very well rendered and colored, marked on the bottom (see last two photos). The collection is composed as follows:
- the large standing one (in the shape of a jug) measures 25 x 24 cm
- the medium seat with tray (like a butter dish) measures 23 x 16 cm
- the large hollow lying area inside measures 34 x 15 cm
- the small hollow lying inside measures 17 x 8 cm (glued beak)
The ceramic has 3 small defects in the penultimate photos which are not at all noticeable and which the price takes fully into account.
