Although only 50 teams make up this collection the clear plastic cards were originally issued in pairs, but they are more often found as single cards, having been separated by the perforation down the centre of the two cards. I thought there were only three combinations for each card which would probably make 75 different pairings. At least one club appears 4 times, so perhaps the pairings are more random and some clubs may only appear once or twice. If you've got pairings not listed please send in details.
NB: Please note that the pairings are shown in alphabetical order and are listed not as they appear with the first club to the left and the second to the right. They are listed by whichever team is first alphabetically.
