Here's a fascinating "long read" piece from Vanity Fair on one of Hollywood's most iconic objects. Comes with a bit of a language warning (real-life characters FTW), but great stuff:
Only when the bidding reached $3.5 million did the bidder in the crowd surrender, sending the Falcon to the man on the phone, who was later revealed to represent Steve Wynn, the Las Vegas hotel and casino billionaire. With the buyer’s premium, the total price came to a stunning $4.1 million. The crowd burst into applause. The auctioneers wheeled out a tub of champagne bottles to celebrate
...
That is the official version of what happened to the Maltese Falcon. But it is just one chapter in a complex tale. It turns out there is another, far stranger version, and another Falcon, several more in fact. And this version, which draws in characters as diverse as Leonardo DiCaprio and the woman butchered in one of Hollywood’s greatest unsolved murders, constitutes a real-life mystery every bit as bizarre as the one Sam Spade confronted on film.
