I believe "Map of Known Universe" (parchment insert) came with this issue (bound-in in some copies, maybe all).
Morty Comix are one-of-a-kind, hand-drawn original art items that were produced by newave comix artist Steve Willis (Morty the Dog, Cranium Frenzy minicomics) between 1983 and 1999 (if not later). The idea was that he would include one in every piece of correspondence and there are over 2000 "issues" floating around (minus any that may have been lost, discarded or destroyed) but they can be difficult to come by. A true rarity of the underground.
In Willis' "A Guide to Morty Comix" (published in the June 2002 issue of the White Buffalo Gazette), the artist notes that although the typical format was something like an index card folded in half (to make a four-page "booklet") there were some variations: Morty Comix drawn on library waste cards, butcher paper, cardboard, foam, wood, etc. Some were produced as puzzles, a couple were 80 pages thick, one was drawn in the sand and sent as a photo.
This one's made from four discarded library cards stapled together with one drawing on each page.
Generally speaking, Not Available printings beyond the 1st have a datestamp on the front or back cover which is the printing date of the batch that copy was from. Matt Feazell says those post-1st printings were usually 60 copies or fewer.
1st printing: March 1996
Other known printings:
March 21, 1996 (1st?)
