Bryan Cranston has just shed a piece of his Walter White persona and donated it to the Smithsonian—Variety reports that the iconic Heisenberg hat and two hazmat suits that Cranston and Aaron Paul’s characters wore on Breaking Bad have just been donated to the museum. A ceremony was held on Monday to recognize the donations from Sony Pictures Television, which produced the series. The porkpie hat and Tyvek suits are the latest additions to the West Wing, which currently holds such notable pop-culture memorabilia as Fonzie’s leather jacket, Archie Bunker’s wing chair, and the puffy shirt from Seinfeld.
