Fun fact: I bought a copy of this record a while ago on recordsale.de...and mine was autographed at the "Crazy Alm" too (but in December 1980). It even came with an extra autograph of Paul Würges inside its sleeve. Whoever owned it before, I just want to say a BIG THANK YOU!
My mono copy has a different back cover where the catalogue of the mono release is listed only. I uploaded a photo of it. Could not find this version anywhere else so far. The record itself looks exactly the same as the labels already shown here.
