Sn claims this series was issued on 2000-12-11 and the IGPC website claims this to. Michel claims this series to be issued on 2002-08-02. Yvert claims this to be a 2002 series. Yvert is the Catalogue of Record for Guinea.
Although this issue was authorized by the Guinea postal administration, virtually the whole issue was not sold in Guinea, but only distributed by the Guinea philatelic agency IGPC for distribution onto the philatelic market.
This issue is still being sold on the IGPC website over two decades later as of the year 2025.
Apparently the Guinea Republic was using multiple stamp agencies in this year.
