Japanese Bobtail - 3D Phantogram GREETING CARD- with 3D Glasses - Image Pops Up from the Card - Unique 3D - This phantogram greeting card is so unique that it will always be remembered. Measuring 5 in. x 7 in., the greeting card comes complete with red and cyan glasses and quality white mailing envelope. You merely add your salutation on the inside and then let the postman deliver your unique message. Unlike traditional 3D images, which are viewed straight on, and can show remarkable depth between foreground and background, a phantogram is viewed from above and at an angle. A phantogram is an optical illusion, a special class of 3-dimensional photography. Phantogram images miraculously rise off the printed pages, perfectly realistic phantoms of the real subjects photographed.
