Making of Final
Printed the cards onto satin photo paper, then cutting the cards as individual pieces, setting the bleed/cropped lines to the desired size so to align cards together. Glued onto 200gsm card. Previous experiments involved using different card thicknesses and glue until I got the desired result as mentioned above.
Before & After card image, altered into an anaglyph.
