May I please jump in here, and ask you a question?

I'm writing my own White Collar story, revolving around an art auction at a reputable and reasonably high-class Manhattan gallery. The gallery owner / art dealer bought the paintings off the original owners, and is now auctioning them - so he will receive all the proceeds.

Does that scenario make any sense to you? I can handwave it in the author's notes, if necessary, but I'd like to know in advance if I'm going to annoy knowledgeable people like your good self.

Alternatively: if the gallery owner were just auctioning the paintings on behalf of the original owners, what cut would he receive of each sale?

Thanks in advance for any help you can offer!
