This seems one emission, but what equal is, is the scouting symbol, the subject « bees » and the value of the stamps (1000).
However the first bloc is issued by the Palestinian National Authority and the second bloc is issued by Rep. Benin. So it will be a joint emission, but the reason is unknown to me. And l am doubting on the Icgality as stamp editor of the Palestinian National Authoritv.
