The first stamps of the Kingdom of Sardinia appeared January 1, 1851, those of the Grand Duchy of Tuscany April 1, 1851, and subsequently those of Sardinia. Cause some concern therefore that the stamps have been
commemorated first of Tuscany (3月 27, 1951) and after those of Sardinia
(October 5, 1951, with this issue), above all it is strange that those of Tuscany, this is the date of issue, while those of Sardinia, is absent.
