what these same technological expertise ,

I'm not too lazy to search in Google about the colors as they look , ie whether it is possible to say exactly when the paint was done . Possible molecular lattice certain kind ... somehow , pictures of this molecule are given to such a year it was not ... or was not as though the paint looks like ...
But there might be a later restoration can crumbling edges or grease stains , especially in gouache ... Can be the " unsophisticated " restoration, familiar artist tidied etc., appeared " later paint " ... This technical expertise must be attentive , take samples from ...

The important thing here do not talk about : the works of famous artists are recognizable , and therefore these artists became known . Each has its own theme , style , character drawing , coloring. Artist gets used to mix some paint, prefer such and not other special effect ... here ... And stuff like that. But it may or may not see museum workers , they are not artists , and not at all accurate eye .
"Investors " new appeal generally do not distinguish anything . And as the need names and not pictures , then it all what we have today ... alas.
