... I'm wondering if that would prove popular....
As an artist, I understand that the painting is signed when I've reached the point where I'm satisfied that it's completed.
However, as an artist I've discovered there are unlikely to be many paintings that I feel I couldn't change .... improve in some way.
Rights of way could be an integral aspect of the sale of a painting, those customers who are completely happy with their painting can waiver, any time. But I may ask them, at their convenience, when I might visit their painting and be permitted to suggest an improvement... by way of this stipulation (contract).
Would Museums approve of that I wonder.....
