Sticker Carré Letter R Stereogram, Set of 6, Large 3x3

*** The LETTER R Stereogram Hidden 3D Magic Eye - Large Sticker (3" x 3"). *** 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.
