An overhead view is shown of the Milhous Collection in Boca Raton, Fla., Jan. 26. With the thud of an auctioneer's gavel, two brothers' lifetimes of collecting will all be gone. Bob and Paul Milhous will complete the liquidation Saturday, Feb. 25, of their one-of-a-kind private museum of antique cars, rare musical instruments and all sorts of other collectibles in a sale expected to fetch around $40 million.
