Is this ad selling the prospect of listening to music in glorious stereo, or the chance to get three free discs from Columbia Records, or something else?

Columbia Records, owned by CBS at that time by CBS (Columbia Broadcasting System), was one of the first to release LPs in stereo in the mid 1950s. Apparently, Columbia also manufactured the delivery device, these beautiful all-in-one radio-record players.

My parents didn’t own a Columbia Stereo. Ours was a Victor, which our cat Miiko enjoyed immensely.
