Hidden Museum presents a cabinet of curiosities--from scientific specimens to antique objet d'art. Behind each intricate illustration in red hides another illustration in blue, which reveals the true nature of the item. Wave the red cellophane magnifying glass over the rock to reveal the geode beneath, or the skull behind the head of the bird. An index at the back explains the scientific significance of each object. A beautiful gift book with a luxurious vintage feel that feels full of mystery and intrigue.
