Pair of large dishes with musicians - Italy 19th century

Two Italian earthenware dishes, certainly part of a series: they are numbered 2/50 and 11/50 on the back with the mark "Mimma Cortina".
The first musician plays the wooden transverse flute while the second plays the "Russian bassoon" or "straight snake". The latter is an instrument close to the bassoon decorated with a snake's head that enjoyed some success in Italy, France and Germany in the first half of the 19th century. Its name has nothing to do with its geographical origin, it would come from the fact that it was used during the Napoleonic campaigns in Prussia and so named by abuse of language.
