Peter's non-flipping tri-cairos was the exchange puzzle of Peter Knoppers at IPP25 in Finland, 2005.
The puzzle consists of 10 pieces and a frame. The goasl is to fit all pieces in the frame, while to mono-cairo pieces are placed at predefined positions. Various challenges are given (see picture 5 6)
The puzzle comes in original custom paper sleeve (picture 3) , which has a few wrinkles.
The challenges are included, the solutions are not.
The original challenge 5 is impossible, it should read field 25 in stead of field 16.
