For whatever it's worth, I had a "Phi Zappa Krappa" poster on my bedroom wall (as a kid, in the early '70s) long before I'd actually purchased any FZ albums.  At the time, this image of him signified, for me, a kind of romantic anti-establishment stance, a hearty fuck-you to just about everyone who ventured into my bedroom.  So even to the nonfan, FZ's visage (not to mention posterior) carried *some* kind of counter-cultural currency, I think.
