Walter Becker, half of the group Steely Dan, died of esophageal cancer in 2017. In 2019, his collection of over 600 guitars, 400 amps and assorted gear was auctioned off, garnering a respectable $3.3 million. Julian's Auctions, the house that ran the auction, has an online "flip book" of the Becker collection, and for gearheads, it's kind of like an "I died and went to heaven" journey to go through it.
