Pôster LETTER R STEREOGRAM 20"x20", Semi-Gloss, No Frame

*** The Letter R Stereogram Hidden 3D Magic Eye - 20x20 Poster, No Frame *** 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.
