In the 1920s, the world was still about 60 years away from the first Walkman, and about 80 from the iPod, but portable music was still apparently a thing. All you had to do was rig a little radio to your garter and a speaker around your head, as the 20s lady in the above video demonstrates.

You also, at that point, had to wear a garter. And you have to wonder how the whole portable thing actually worked, because there couldn't have possibly been wireless MP3 player-sized devices. But the Discman, the Walkman, and the iPod are all thanking this woman—and her inventiveness—for their important contribution to society. [OhHaveYouSeenThis]
