The deviously puzzling Sandfield brothers, Robert and Norman, designed their Salt and Pepper Shakers to exchange at IPP 22 held in Antwerp in 2002. 

Kamei created a number of “Love Box” puzzles shaped like little hearts.  No. 5 is a cute little piece in dark wood, with a bright yellow wood ribbon, and a red cloth lined secret compartment.

Japanese master Yoshio Okiyama, was a third generation secret-box maker who was taught by his father, Yoshitaro Okiyama, who in turn was taught by his father, Tatsunosuke Okiyama, one of the 3 original founders of this art form dating back to sometime after 1870.
