Henry Winkler, the affable actor who played small screen icon Arthur “Fonzie” Fonzarelli on Happy Days, is selling several pieces from his collection. Among them, is one of Fonzie’s signature leather jackets.

The Henry Winkler Collection will be auctioned on December 8, 2021, at Bonhams Los Angeles. The leather jacket in the auction is one that Winkler has had in his personal collection for decades. It will be sold as part of a Fonzie outfit, complete with an original t-shirt, jeans, and biker boots.

A pair of mechanic overalls he wore in the 1950s-set sitcom are also crossing the auction block.

In addition to Happy Days, the 26-lot auction will feature costumes and props from throughout his career. These include a Ghostface mask he used in Scream, a jacket he wore in Night Shift (directed by Happy Days costar Ron Howard), and a pair of cowboy boots he wore in The Lords of Flatbush and later as Fonzie.

Part of the proceeds from the sale will go to the nonprofit This Is About Humanity that was cofounded by Winkler’s daughter Zoe.
