Here is my exchange puzzle from 2011 IPP31 designed by Juno (Junichi Yananose) and made by Brian Young (Mr. Puzzle). I have known Brian for many years as we live close to each other and he introduced me the IPP community when they came to Australia. I auctioned one of these puzzles to find out what the market us prepared to pay so this is a buy it now auction including postage anywhere in the world. Price is in US dollars.
