Monster Brains has released a full scan of The Official Advanced Dungeons & Dragons Coloring Album. Illustrated by Greg Irons (deceased, 1984) it was originally published in 1979 and is currently out of print. From the Monster Brains blog:
I’ve chosen to share the entire coloring book for anyone interested in printing it out and coloring it themselves. Every page is included in order. I don’t normally share copyrighted material in its entirety, however considering this “coloring book” has been out of print for over 30 years, I feel this thing deserves to be shared. If copyright holders of this book are opposed to my sharing it, feel free to contact me and I’ll remove it by request.
Have you downloaded it yet? Is your basement festooned with your daughters’ D&D handiwork?
