IMPERIAL DOUBLE NINES DOMINOES WW2 1940s/50s
Made of a black, bakelite-type material the spot depressions are painted white. For those that like spinning the dominoes (a la pub style), the moulded tile has a rivet-like proud circle in the middle of the dividing bar to allow it to do just than - spin - when upside down.
