First one to discover the illusion this poster hides gets an A+! Just don’t be distracted by the looks of the lady in it! I’m afraid the illusion has been incorporated with help of Adobe Photoshop or similar tool (which makes it less of an illusion, and more of a hard-to-see thingy), but still no less interesting find!
