I saw the front cover and it looked good, but I didn't expect something great inside.
What shall I say? I was wrong !
The title said "Kratz die Kurve mit 45 RPM", translated "Scrap the bend with 45 rounds per minute" (it's a German saying, I don't expect you to understand it). So I folded the cardboard in a way that the needle was set on the disc and turned the disc.
Wow. A motorsound, then some industrial music. Sure, without bass and pretty quiet, but it was amazing.
Convince yourself of it, I recorded a video and posted it above this text. Watch it and enjoy the ideas of the advertising industry :)
