MB Operation ad from the 80’s
Operation is a battery-operated game of physical skill that tests players’ hand-eye co-ordination. Made by Milton Bradley, it has been in production since 1965, the year in which the game was invented by John Spinello.
The game is a variant on the old-fashioned wire loop electric game popular at fun-fairs and the flammer stores around the United States. It consists of an “operating table”, lithographed with a comic likeness of a patient (nicknamed “Cavity Sam”) with a large, red light-bulb for his nose. In the surface are a number of openings, which reveal fictional and humorously-named ailments made of white plastic. To work, the game requires two AA batteries.
