Autostereogram Stamps
An autostereogram is a two-dimensional (2D) image that can create the optical illusion of a three-dimensional (3D) scene. Autostereograms use only one image to accomplish the effect while normal stereograms require two. The 3D scene in an autostereogram is often unrecognizable until it is viewed properly. One needs to stare at the scene for awhile for the 3D effect to emerge. Guernsey Post issued a set of 2 stamps featuring design of a dove, a universal symbol of peace, one with a green background 25p stamp, and a blue background 30p stamp. Designed by Keith Bassford, the Autostereogram (a hidden image seen by crossing one's eyes in the correct way) was created by David Burder (UK) and Bob Mannle (USA). The hidden images are large versions of the doves as featured on the patterns i.e. on the 25p stamp the bird is standing, face to your right, while on the 30p stamp it is flying to the left. Autostereograms can also be found in art. An example is by renowned Cebuano color b
