What's good for the goose being good for the gander, here's a set of scantily-clad gentlemen showing off both their steampunkiness and their physical assets in a sort of "steampunk beefcake" genre. Note that many of these images are included in the "Gentlemen of Steampunk" books (which include fascinating biographies of their characters) and calendars.
