Above and below: work in the home of Frederique Reboul, which might be by her, seeing as there's alot of it, and she is listed as an illustratrice in the introduction. As you might already know, Paumes' books are mostly in Japanese. It's about the pictures anyway, but at the same time it would be nice to know more. [ February 15: news flash....here is a link to her blog Lili Scratchy -- thanks so much to super Jaboopee!]
Above: this clever soft toy in the home of Patricia Rindlisbacher and her two boys Sid and Larsen is definitely her work. I figured that out by myself. See more clever things inspired by her two sons here. Incidentally, her's looks to be the only non-nuclear family in the whole book. Interesting.
