169 (4 football)
An alphabetical compendium of information, the slips were punched with two holes for inserting into special binders. I don't have illustrations of the football slips so I've included a couple of others as examples.
UPDATE (22-05-2015): I've now found one of the football slips. The slips measure approximately 3.8" by 2.4 ".
