Fans of Terry Pratchett’s Discworld series will probably know that Paul Kidby was the illustrator for the covers of the later Discworld books. Since 2002 he’s been the artist who’s done the covers and art in various books related to the series. The Terry Pratchett’s Discworld Colouring Book is full of line art versions of some of his art. In total there are 77 pages to colour in, 78 if you include the title page and 16 pages of the original full colour art for the line art versions in the book.
This colouring book has images from various stories, along with excerpts from the books themselves on a lot of the pages next to the full page images and surrounded by their own art too so you have the link to the Terry Pratchett works there too. It’s been around for a couple of years, it was first published in 2016, but somehow I’ve missed it. I think it came out just after I’d bought a few too many colouring books and was taking a break but it’s in my collection now.
