two from Africa

I have only a handful of stamps from African nations, but just ran across several at once. Here is a pair from Ghana. And an unusual pair at that - the Queen of England together with a fertility doll?? It was random chance, how they came to me.

日本語 hints
only a handful = a very small number of
run across = find by accident; and unplanned discovery
fertility doll....someone help me here. I find things like 生産力 and 豊穣 in the dictionary, but that doesn't feel right.

Also, notice that "pair", even though it contains two items, is treated as singular for grammar purposes: This pair of stamps IS from Ghana.
