There was a time when these were used mainly as an aid to sales and covered many sports and other things such as cars, planes and trains even works of art and historical characters. If my memory serves me right they were also issued by purveyors of other products such as tea so they must have been a good way to increase sales - now they are still a collectors item and some of the rare editions are worth a small fortune. Fortunately the sport of speedway did not miss out and there are cards depicting riders from very early in the sports British history. It is my opinion that these cards form a part of the history of the sport of speedway and their existence shows the important part our sport formed in the everyday life of people at that time.
To my knowledge only two tobacco manufactures issued these cards Player’s whose complete set had 50 cards and Ogden who had a set of 25.
