Things are not always as they appear. Optical illusions confuse the eyes and the brain into perceiving things that may not be there. Tease your brain with twelve mind-blowing images that fascinate and amaze as you try to make sense of what you are seeing...is it real, or not? The calendar pages are printed on FSC Certified paper.
