Here's a wheel that actually says it's handy!
Isn't this magnificent? There is something about the graphic design of this wheel that reminds me of the old 1920s Russian movie posters. Maybe it's the steely optimism of a mass of tangled nails tumbling out of the inky blackness of an impossibly small barrel that screams, "Industry! Productivity! Work!" that does it for me.
This wheel measures just 9.5 inches (10.5 if you count the extension) and has a greasy film on it. I wonder what kind of workers' paradise this was used in?
