ESSO 1970 world cup (blue card display board)
The grand-daddy of all football coin sets (but not the first), the ESSO 1970 world cup coin set is the wonderful forerunner of many subseqent collector sets. This is the blue firm card collector board which you had to pay for - see also the flimsy red paper folder.
I won't spend much time on this set as there is an enormous amount of reference material online. Look out for the employee sets cast in bronze!
