Make the ultimate 3D optical illusion while learning 1-point perspective! Based on the artwork of Patrick Hughes you can now help students practice perspective and trick their eyes all in one. This version of the Reverspective works with 1-point perspective. This product works best when attached or printed on sturdy ground like cardstock or posterboard. Reverspectives should be displayed at eye level for best effect. Blank templates and rooms without watermarks are also available in the store.
