I just cannot find this listing in Scott; I have the 2012 catalogues and even though this clearly shows 2002 on each stamp, I can't find it. Anyone with better eyes or perseverance able to identify this by catalogue number and value please?
Your sheet will most probably be listed in the Westafrika Michel catalog (Volume 5). Unfortunately, my catalog is the 2001/2002 edition, and only lists Guinea issues through 1998. Perhaps some otther member can look it up for you.
