Artist and designer Michael Lexier created this curious object, "Two Puzzles," in which the image of one puzzle's cuts is printed on the other, and vice-versa.
"They look like two of the exact same puzzles, but are in fact different," Lexier writes on Instagram. "One is the image of the nine-piece puzzle foil-stamped on to the 16-piece die-cut puzzle and the other is the image of the 16-piece puzzle foil-stamped on to the nine piece die-cut puzzle."
An edition of 100, each puzzle is 4 x 5.5 inches.
