I'd been meaning to pick up a copy when I saw it, but I never managed to find one in a shop til this week. Do Not Open This Book is perfect picture book simplicity. The funny little blue guy gets angrier and angrier as you keep disobeying him and firstly open the book and then turn each page.
It is reminiscent of 1971's The Monster at the End of this Book, and there was a small skirmish about this at the time of publication, but I don't think that anything has come of it. Indeed there appears to be at least two other books called Do Not Open This Book- a 1998 book by legend Joy Cowley, and a 2006 one by Michaela Muntean.
Do Not Open This Book was published by Lake Press, a small independent publisher based in Melbourne that has been shortlisted for Best Children's Publisher Book Publisher 2017 in Oceania at the Bologna Book Fair.
