Wondermark's steampunk helicopter

Dave from the Wondermark webtoon sez, "Hi folks. I made a steampunk helicopter for my most recent Wondermark comic. It's collaged together in my usual fashion from scans of old Scientific American magazines. I've been making helicopter noises with my mouth as I walk around this morning and realized that I'm just super duper proud of it, so I thought I would share. Thanks, hope you like it!"
