The cover shows a strange post-apocalyptic field with ancient TVs picking up old broadcast signals.

How'd they get there? Well, inside we first see some scientists carrying TVs out into the field...

They place them and test for broadcast signals. To pick up the ancient broadcasts, they need to be in a spot without trees or buildings to interfere... thus the big empty field.

Now that the old TVs are working, the researchers ask their impressionable test subject to turn them on. Good thing she finds an old broadcast of Margot videos.
