Cartão GIRAFFE STEREOGRAM 7x5 Greeting

*** GIRAFFE STEREOGRAM Hidden 3D Magic Eye – GREETING CARD, 7X5, With White Envelope *** But what is a stereogram? In simple words, a stereogram is a picture within a picture. It is an “optical illusion” art where you can see a totally different image in 3d form beyond a series of ordinary patterns. The seemingly ordinary 2d picture creates an awesome, almost magical impression of depth; when viewed in a certain way, the deep 3d image will just be floating before your eyes! And yes, no special eyeglasses needed.
