The most humble of games but beloved of Tap Rooms and Social Clubs up and down the North . 
My Grandad was a champion Doms player (at least I thought so) and this wee set of ‘bones’ is a fine example. Not too tiny to lose but small enough to slip in a big pocket to amuse on long journeys or autumnal evenings.
(Last pic shows comparison with a standard set of Doms) 
Original slide top box with 28 beautifully made bone and ebony dominoes with perfectly raised brass studs allowing the dominoes to magically spin on the table.
