The original sheet music cover for Watch Your Step (1914) gives you an idea of the ornate, colorful style that dominated theatrical memorabilia and advertising in the 1910s. The score by Irving Berlin included several hits, most notably the counterpoint "Play a Simple Melody," and the less well known "When I Discovered You."

Perpetual Motion Norman Rockwell 1920
 Cover of the October 1920 issue of Popular Science magazine, painted by American illustrator Norman Rockwell. It depicts an inventor working on a perpetual motion machine. The device shown is a "mass leverage" device, where the spherical weights on the right have more leverage than those on the left, supposedly creating a perpetual rotation, but there are a greater number of weights to the left, balancing the device.
