The World Cup Souvenir Cards were produced to acknowledge
'England World Cup candidates plus international stars of world
renown'. The cards were obtained by cutting out coupons which
appeared in the Daily Sketch. You needed to collect 5 coupons then
send them to the newspaper who sent you 5 cards (as a strip of 5).
The first coupons appeared in the newspaper dated 23 February 1970.
These transfers were issued as two sheets, each of 14. They were
often cut into single transfers and stuck onto school books. I'm not
sure how you got them or much more about them. The stickers were
designed to be stuck onto the Daily Sketch 1970 World Cup Picture
