I have an oil painting by the signed by the name stefano its an oil painting of a vase of flowers on a table can you email all signatures by the name of stefano I googled the artist stefano and more than one artist is coming up I need to identify by signature. The size is height 21"x24"

Maybe you should take the painting to an art dealer so they can tell you what you want to know.

That is what I would do if I was you.
