Redheads matches used to run series of collectable pictures on various topics on top of each box. You cut the empty box with scissors and kept the top. I don’t know how many were in a series, about 15, but it was just enough to fit in two stacks in an orange Erinmore Flake tobacco tin. That could be carried neatly in a boy's pocket. The availability of both tells you something about my dad.
I tried to Google the subject but kept getting matchbox toys rather than box tops.
