It was 1997 and the Star Wars Special Editions had just been released. Walkers Crisps (Chips to those in the US) released a set of 50 limited edition Tazos; small round collectable cards with an image on.
There were fifty to collect. The first 39 portrayed images from the original three movies, 13 for each. The final 10 were special images from the Special Editions- you could only find those in packs of Doritos.
You could also buy a special binder called the Collector’s Force Pack to keep them in. It was a fairly sturdy folder with images from the films and a short quiz inside.
