File this one under primitive multimedia concepts. Published in 1960,
Theatrorama was a short-lived spin-off from the more successful
Sonorama magazine. Where
Sonorama focused on singers and celebrities,
Theatrorama gave readers/listeners an entire play in book/flexidisc form.

The idea was that you could enjoy the entirety of Jean Anouilh's
L'Hurluberlu from the comfort of your favorite armchair in front of the old hi-fi, getting up occasionally (say every seven or eight minutes) to flip the object over on your turntable.

Just to add to the verisimilitude, you could of course pause now and then to take in a riveting photo from the stage production.

As with
Sonorama, this mag gave you six 2-sided flexis, glossy paper and semi-reliable plastic ring binding. And of course a one-page hawk for the parent publication.

As far as I can tell (ok, one Google search),
Theatrorama lasted a mere two issues. Copies of this sell from between 1 and 60 euros, depending on your vendor. If anyone's interested, I'll take 60 please.
I'll leave you with a cool ad from the inside front cover:
