Good Poop from 1982
I love this vintage dealer supplement (ugh, I can't believe I just called something from the 80's "vintage") titled "Good Poop On Who's Using Klipsch." Especially the small inset on the back titled "A Little Poop About The Klipsch MCM System." Crude? Perhaps. But then again, so is "Bullshit."
You can download the full brochure to see who was using Klipsch back then.
