It's the second Saturday of the month and that means Steampunk Saturday! Here's an image from the May 1921 issue of Popular Mechanics that would look right at home on the set of Iron Skies. Fresh from the hell of the World War I trenches, the American military had mustard gas on the brain and this little number was their answer to the horrors of chemical warfare. Me? I see this being worn by a mad scientist, probing the mysteries of the aether or a high-altitude airship raider.
