Many thank for the best matching font

Didot Medium Italic  Suggeriti da jerseygirl 

or Bold Italic

Merci de votre réponse mais DIDOT ne semble pas la bonne font... la forme du "g" ne convient pas !

Not the good font my friend... the "g" isn't the same...

!

Taking into account that you supplied a jpg, the perfect match is Hoefler & Frere-Jones' Didot HTF B64 Bold Italic. So why the muttering?
