Much like this chess set from 1975 [1]. We picked it up from an auction house about 6years ago, but didnt pay anywhere near the price it reached at bonhams. It is really well designed is "travel ready" put on lid and all pieces stay in place. With only 12 supposedly made it was a great find. edit:forgot to mention who made it Ove Arup (who founded the Arup group) [1]https://www.bonhams.com/auction/19097/lot/49/a-prototype-archeso-gemini-chess-set-by-sir-ove-nyquist-arup-the-arup-chess-company-london-1975/ https://www.bonhams.com/auction/19097/lot/49/a-prototype-arc...
