Is the Klaremont collection a car dealer?

I ran across pictures of a 100-car plus collection in Chicago, website says it's a museum, no sign on the site of a car for sale. But it's odd that there are purebred cars, like prewar Rolls Royces, and then fake old cars like Clenets, and then wanna-be George Barris-style customs. Most of the guys I know that own the real thing wouldn't bother with replicas. I realize every car museum, has excess donated cars and sells them but maybe some Chicago resident can tell me what this place is so I can see if there's a car for sale.
