My name is ***** ***** I would be happy to help with your Capodimonte figurine.
He was made by the Italian artist/modeler Gino Pezzato who produced a whole series of charming children figurines from the 1950s through the 1970s, very much in the style of Goebel's Hummel figurines which were so hugely popular at the time and these were clearly produced to cash in on that popularity, -what I call a "me-too" operation.
The signature on the base reads G. Pezzato though you'd be forgiven for not being able to figure it out as the "P" has not impressed properly.
Each of the figurines came with a Certificate of Authenticity tag confirming that the piece was made in the traditional way that was done at the original 18th century porcelain manufactury in Naples, the "Real Casa Capodimonte" (the "Royal House of Capadimonte") and stamped as such with the crowned N.
Having said that, there's no direct connection with the original Capodimonte. After it ceased production forever in the mid-1800s the crowned N mark came up for grabs and has been used Europe-wide ever since by scores of factories, each one trading on the recognition of the royal mark. The Pezzato factory was just one of them. It was located in Creazzo, near Vicenza, in Northern Italy and nowhere near Naples.
As for value, these Pezzato figures do have a modest following of collectors. If you were to see your little boy doctor for sale in an antique shop, for instance , he would have a full retail value of about $75. This is also the replacement value for insurance purposes.
Expect to get 30% - 40% of this if you were to sell at a good antique auction house or on line (eBay etc).
I do hope this helps!
Please let me know if you'd like me to explain or expand further, I would be glad to.
