I don’t think it’s by the hand of the master because it has no resemblance to anything else he ever did (in terms of brush strokes, line, etc.).

It may be from his studio, however, because artists maintained a stable of people who either copied or executed their works, that is, translated a sketch into a painting.

It’s still very interesting. The style, to me, looks like a curious combination of modern, looking at the faces of the Virgin and St John, and pre-Renn, looking at the setting combined with the depiction of the Infant.

I think it’s a workshop production, and I believe there may have been a Spanish painter involved, based mainly on the depiction of the Infant.

Leonardo, indeed, had a workshop. One of his artists was a fellow named Giovanni Beltraffio. Another was Marco Or...something or other. It's chronicled in the wonderful historical novel “The Romance of Leonardo Da Vinci” which is based on Vasari’s biography of the one and only Chairman of the Board.

I don't think it looks like his work at all.
