"Patrick MacNee “John Steed” signature bowler hat from The Avengers. (ABC TV, 1961-1969) In this beloved British “Spy-Fi” TV series, Partick MacNee began as an assistant and by the second season graduated to the star of the show, sealing his fate as a pop-culture icon. For the better part of a decade, MacNee portrayed “John Steed”, the dapper sleuth with a bevy of beautiful assistants that changed like the seasons, as he remained decked out in tailored suit, tightly wound umbrella and, most importantly, signature felt bowler hat. This bowler hat is custom-made by Herbert Johnson in brown felt, size 7.75, featuring silk lining and inner leather hatband. The bowler hat was personally given by Patrick MacNee to the Michael Bolton Foundation for charity auction and remains in fine condition. Accompanied by an 11 x 14 in. vintage black and white photo of MacNee in character as “John Steed”, inscribed by the actor in blue pen, “To the Michael Bolton Foundation - Very Best Wishes - ‘The Hat in the box is exactly the same as the one on my head’! Pat MacNee”. Photo shows wear, edge chipping and lower right corner damage. Provenance: A Summer Musical Spectacular benefiting The Michael Bolton Foundation, Sunday, June 25, 1995. Lot 100.

London auctioneer Christie's offered on 29th November 2012 an original bowler hat from The Avengers series.
