I love it -- in fact, I not only wrote a handful of reviews for it, I will also be writing an essay for a collection on Tove Jansson and a conference that will be held at Oxford in March. The hardcover edition has lovely cream color pages and a nubbly feel to the cover. The beauty of the drawings is enhanced by D&Q's attention to detail. They really think about the book as an entire work of art. I can't imagine anyone doing a better job with these terrific stories and Jansson's singular style.
Buy it! You'll be glad you did.
