You have an Italian majolica pottery bowl from the Santarelli factory which was located in the town of Gauldo Tadino. While it was not decorated by Santarelli himself, it was most certainly executed by one his more talented decorators. The writing displayed on the base is typical of that in use from about 1910 through the early 1940's.
Pieces from the Santarelli factory have always been highly collectible and remain so today but that is for his artistic ceramics. This bowl was meant simply to be used as everyday tableware, called stoviglieri in Italian.
This bowl has a current value of $400 to $600 retail.
Below is the passage about Santarelli as it appears in my book.
"Alfredo Santarelli (1874-1957), born in 1874 into a family of horseshoers, opened his first workshop in the 1910 in Gauldo Tadino. Santarelli’s renown as a ceramics artist was well known long before he opened his own operation. The shop was located in the same building where the 17th century ceramicist Francisco Biagioli had his kiln. Between 1899 and 1927 he garnered more awards than perhaps any other artist of the time. He talent even caught the eye of the royalty. King Vittorio Emmanuelle II was so impressed by him that in 1925 a decree was given that allowed Santarelli to display the Royal Coat of Arms in his catalogues."
