I wouldn't admit to any of those paintings either.
I'd ignore the paintings, but I'd accept the millions $$. It's interesting how people pay millions of dollars for paintings like that. Maybe they look on them as investments.
That's what the lawyer mentioned, but I don't think he could deny it. If the gallery paid $1 million because it was done by a famous artist, and then the artist falsely denies having painted it, that would make the painting worthless.
