I spent a bit of time this morning looking through holiday party archives to see how it was all going down in a time before Substack and Instagram-bait cakes and sensitivity training.

This story from a December 1996 issue of The New York Times explained how Wall Street consciously celebrated a booming market with Tiffany boxes and $190 bottles of Cristal (that would be about $390 today).

More recently, in 2010, a young Kevin Roose covered Blackstone’s 25th annual holiday bash at the Metropolitan Museum of Art for New York Magazine — “trophy wives in furs, back-office workers talking about the Knicks, fresh-from-Princeton analysts laughing too hard at their bosses’ jokes.”

If you have any fond New York workplace holiday parties you want to reminisce about, see you in the comment section.

  • News broke this morning that Brad Lander is planning to launch his bid for Congress.

  • The Hermès family has quietly been building up Krefeld, their family office. According to Bloomberg, they’ve quietly created a separate company within it, called Breithorn Holding, to handle fund and asset management. The 100+ heirs to the Hermès family fortune reportedly have a combined net worth of $186B, making them the richest family in Europe.

  • The estate of Grace Mirabella, former editor-in-chief of Vogue, is up for auction at Showplace. It’s unusual that zero publications have announced this yet, especially since there are tons of items up for auction that news editors will go crazy for. We reached out to Michael Grynbaum, the premiere historian of all things Condé Nast, who said he plans to bid on a few pieces himself: “I love the Helmut Newton and Deborah Turbeville prints, and the rare abstract canvases by Alexander Liberman, the legendary Condé editorial director who discovered Avedon and Penn. (Liberman was an accomplished artist in his own right and his work is rarely up for auction.) These handsome bound volumes of Mirabella (attn Library180!) and the vintage Vogues look really fun. If I had to pick just one... maybe this insane Irving Penn photograph of Miss Piggy??”
