Deceptive pitcher Nevers earthenware blue monochrome gallant scene shepherdess 18th century

Deceptive pitcher known as a surprise pot in Nevers earthenware with blue monochrome decoration of characters in a bucolic scene: a gallant scene with a couple in the center, a shepherdess and a shepherd with their flock of sheep, as well as a dog running in the landscape, openwork upper part, from the 18th century.
This pitcher is in good overall condition.
Please note: some chips on the neck and base, enamel defects, wear and tear, see photos.
________________________________________
* The deceptive pitcher, also called a surprise pot, is perforated, making it appear impossible to empty. Drinking can only be done by sucking through one of the small horizontal necks located on the hollow rim that forms the edge of the upper opening. This communicates with the body of the container through the handle, which is also hollow.
Deceptive pots generally have a globular body mounted on a more or less marked pedestal, a cylindrical or slightly truncated neck and a curved handle.
Use: The object is used to surprise and entertain because the "victim" will be disconcerted when the contents of the pitcher spill next to their glass.
The fun then continues with the discovery of the "trick" that will allow the contents to be drunk without spilling. The "victim" will easily find the hole at the bottom of the belly, which corresponds to the lower attachment of the hollow handle.
And will naturally think of emptying the pitcher by sucking through one of the necks.
After several attempts, the last secret of the pitcher will be revealed to the discouraged one.
It will be enough to obstruct the small hole discreetly placed under the upper part of the handle that the user himself hid when holding the pot.
