In 1997, I was commissioned by the Intergovernmental Philatelic Corporation to produce 9 portraits of President Kennedy. This was the first time that I had made so many portraits of the same person in a row for a commission. They were issued from the little island country of Maldives. The stamps can still be seen on this site: https://www.stampworld.com/en/stamps/Maldives/Postage%20stamps/1990-1999?user=0&year=1998 Scroll down to the 8th image and you can see them.
