Still Life & Street - 3d STEREO VIEWER Note Card
   by MC Escher

This black and white 3d Stereo Viewer Card is a reproduction of Dutch artist MC Escher's famous Still Life & Street tessellation.

Working in much the same way as the Currier & Ives stereoviews of the past, the card operates on the venerable principle of the stereopticon.

This steroviewer has a nearly identical image for each lens (right and left) - and of course, there is a cut-out for your nose. You can even adjust the focus - just squeeze the folded-out card. (No 3D glasses are necessary - this is a different process altogether!)

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!
