The Galactic Zoo Dossier is a hand drawn psychedelic magazine occasional published since 1995 by Plastic Crimewave, and has been published by the good folks at Drag City since 2001. The mags originally came with cassettes and posters, but current issues come with a CD compilation of rare sounds and trading card sets of damaged guitar gods and astral folk maidens.
Issues 1-4 were self-published but were collected into a now sold-out book collection by Drag City, the GZD Compendium.
Issues 5-7 were published by Drag city but are also sold-out, though some copies of GZD #6 have been unearthed as well as extra trading card sets from GZD #6-7, check the drag city site and this site for details.
A brand new issue is due in spring of 2009, if all goes well!
