Bop 'em beep-and-blink punching toys

This 1966 ad for "beep n' blink" Bop 'Em punching bags is interesting: I remember nearly identical ads from the mid-1970s, when I was old enough to pore over the Consumers Distributing catalog and show my folks what I wanted for Christmaskah. Funny to think of an electronic toy whose design and marketing hardly changed over an entire decade.
