Today, October 22, 2017, marks the 70th anniversary of the introduction of the flipper. Congrats! The images below I borrowed from Michael Gottlieb who shared them about a month ago. They're from a 78 rpm record that was recorded for the 1st anniversary of the flipper, which informed me the precise date of the 70th anniversary. The flipper was first used on Gottlieb's Humpty Dumpty and changed the industry forever.
