You'd be surprised how easy it is to get your hands on these comics, Labyrinth a bit moreso than Dark Crystal. When they were released in the 80s, they first came out in magazine format as Marvel Super Specials. Then they released the limited series of each book, which basically cut the Super Special up into about three or four issues. These days you can find the comics in the bargain bins of most any comics shop. They never really went up in value, and were little more than hastily slapped together publicity pieces. However, Bret Blevins did his first work for Marvel comics on The Dark Crystal, and anyone who saw his run on New Mutants in the 80s knows how talented he was, and it shows in the Dark Crystal. And Labyrinth had uber-brilliant Marvel artist John Buscema as the penciler, and that man knows how to draw fantasy (and dang near anything else). So though the writing on these comics was sub par and they weren't necessarily the best representations of the movies, the artwork is stunning in both cases. I still have both the Super Specials as well as the limited series for Labyrinth, and they're always good for quick shot of nostalgia.
