By jan pienkowski. I have a new obsession with this guys pop up books. So i bought this gorgeous book second hand but was told it was in goid condition. It is but i don't know if the vendor realused there's supposed to be a hidden paper with clues to where the pics are. Either it's extremely well hidden or i'm missing it. Don't suppose anyone could give me a transcript or email a photocopy to me? Or even tell me where it's supposed to be hidden? (is it in the bookcase?)
