Jim Henson’s Dark Crystal is a classic to many—and with Netflix’s recent announcement that they’re bringing the world of Thra back to life, it’s interesting to look back at the groundbreaking work that went into the 1982 movie. A new book promises to do just that, and we’ve got an exclusive look inside.

Published by Insight Editions, Dark Crystal: The Ultimate Visual History gathers tons of rare and unseen pieces of concept art as well as behind-the-scenes pictures from production on the film, 35 years after it was made.

Promising to chart Henson’s personal journey making the movie day-by-day as well as providing insight into the landmark puppetry that gave us the film’s lovable cast of characters, it’s the perfect thing to catch up on while counting down the days to Netflix’s new prequel series. Check out a few spreads from the book below, making their debut here on io9. Don’t forget to click the magnifying glass to enlarge them (and then open them in a new tab to see them at full resolution!)


Dark Crystal: The Ultimate Visual History is set to release this September.
