Omg. I remember it well.
My dad used to have to complete the figures on the board from the record cards/reports. I spent many a childhood Saturday afternoon gluing the back of the red and black squares to pass to him to stick on the big wooden board. What fun! when all my school chums were out kicking footballs and enjoying the day I was on my knees on the lino of our rented hall gluing tiny squares of paper.
