Who is depicted in the portrait?
 

I ask for help from forumchan.
Please'll show who represented the Kings as a child in this portrait?
Who is the artist?

Olden, this is hardly a king, probably the son of master workshop, painting as a gift from the slave master. I think it is enamel?

This is a porcelain layer on which a copy of a famous painting.
Somewhere I met earlier this portrait. I can not remember.
I tried to search through Google and found nothing.
I do not know which side to approach the right to ask a question.

Can a porcelain factories? But still so easy to nobody will transfer portrait on porcelain. This is not an ornament. Not run out.

uriart, I, too, seemed familiar. But not quite the king.
See it?

Well, all the same ... The son of Grand Duke of Tuscany. :)

Seema, thanks!
So who is it?
Something vaguely remember that, of the kind of Valois?
Do not you?

uriart, as well as of Valois? I think of the Medici. However, they also were related.

 The son of Cosimo I de 'Medici, Duke of Tuscany (12 June 1519-21 April 1574) Giovanni, future date, Cardinal, Bishop of Pisa.

Cyril Syzransky, thanks!
So who is the author and the work itself?
