1970's Go Board in Cornwall

My 13 year-old second cousin, whom I taught how to play when she was 8, which was the last time I saw her until today, bought herself a 50p go board from a charity show deep in the English countryside. Judging from the box, the board looks as if it was made in the 1970's. The stones are small, wooden checkers pieces.

Finally, another go player in the family. Vindicated.
