Vintage Chinese Plexiglas Puzzle, Circa 1970s

Vintage "Diamond" puzzle, designed in the style of Max Souze, in acrylic glass / lucite / plexiglass / altuglas, from the 1970s. Also known as the "Casse Tête Chinois" puzzle in French, it is made up of 6 individual pieces (see photos) which, when fully assembled, resemble various diamond shapes (see photos). The piece is in overall good, original, vintage condition, with some light marks, signs of age, micro-scratches and previous use commensurate with time, as well as a patina of time, on the overall structure, sides, edges and corners. Some small marks of use on two corners (see photos.) All photos are taken in natural indoor light, therefore colors may vary depending on the brightness, reflections, angles and perspective from which they are viewed.
