There is a few versions of this record, it’s an “add on” 5-inch vinyl for the Gæoudjiparl Mort Aux Vaches CD, Staalplaat 2005. All versions of the record are micro-engraved and looks great. The disc was, as far as I’m concerned, never sold with the CD from Staalplaat but only from the hand of the Goodiepal to record shops and concerts and so on. I believe the code, that st1z mentions, is referring to the tracklist and the original hyperlinks of the Staalplaat CD (two links to the artists Voks and T.S. Hoeg), which would be a typical Goodiepal-ish act.
The vinyl or vinyls, if you like, holds great micro-engravings just as the V/Vm “vvmt24” release he did a few years back.
