There is a geographical pattern to the distribution of beekeeping (as mapped by the cards). It isn't terribly easy to see, but it is there.
Should your eyes grow tired, you might consider this question instead: Among the Zaporozhian Cossacks who inhabited the southern reaches of the Dnieper River (modern day Ukraine) from the 15th to the 18th century, hunting, fishing, beekeeping, salt-making, and cattle raising went hand-in-hand. By the time these playing cards appeared, their lands had long since been incorporated into the Russian Empire and reinvented as Yekaterinoslav Province. To what extent did beekeeping continue to go hand-in-hand with fishing, salt-making, hunting, and cattle raising?
