Right now, hats made by Bill Cunningham are up for auction. I found out from the NYT article
https://www.nytimes.com/2025/03/19/style/bill-cunningham-william-j-hats.html
which is full of some great tidbits and photos of the purchasers (and behind a paywall, apologies)
The photos of the hats themselves are on the auction website. More than just these four.
