The only way we can think to describe these is way cool! Working in much the same way as the Currier & Ives stereoviews of the past, these operate on the venerable principle of the stereopticon. The viewer does not use the 3D TV Glasses with one blue and one red lenses. These cards, instead have a nearly identical image for each lens - and of course, there is a cut-out for your nose. You can even adjust the focus - just squeeze the folded-out card.
There's a space for a short message and the whole card folds flat for mailing in the envelope provided. Perfect for the occasion when a gift is too much and a card too little!
Dutch artist Maurits Cornelis Escher (1898-1972) was and is one of the world's most famous graphic artists. The left-handed artist is best known for his impossible structures and amazing three-dimensional woodcuts and drawings. He was consistently fascinated with congruency, perspective and technique: often spending hours experimenting.
This black and white card is a reproduction of his famous woodcut Still Life & Street, originally created in 1937. A small street in Savona, Italy, was the inspiration for this special work. Famous for his enigmatic images, in this special work, there are two realities bound together in a seemingly realistic, yet honestly impossible, way. The street is seen from the window. Escher has made the outdoor houses appear as though the indoor books rest upon them. Escher has eliminated the border between the window and the street, allowing all the objects to merge, almost creating another dimension.
