St. Vincent & The Grenadines did a few of these in 2000 to
celebrate the Queen Mother's 100th birthday (I notice the
issue date was September 5th, my Father's birthday, as well.)
It is in the form of a photomosaic, and as the legend beneath
the portrait states, "Photomosaics is a method of arranging
thousands of tiny photographs that when viewed at a distance,
combine to form a single larger image. Robert Silvers invented
this technology while still a student at MIT and founded Runaway
Technology in 1994."
The Queen Mother's portrait was created using tiny photographs
of flowers. The souvenir sheet contains eight $1 stamps and is
Scott 2816. It measures approximately 6-1/4 X 9-1/2 inches.
