Here is a sample of my most recent thematic collection: blind on stamps. A rich theme where we can find, for instance, Louis Braille, the French man who devised the Braille system. In 2009 we will celebrate the 200th anniversary of his birth and postal services worldwide will certainly issue commemorative stamps on that date. Guide dogs, oftalmology, causes and prevention of blindness, famous blind persons and many other subject areas compose my collection. I collect mint stamps, FDC, miniature sheet...everything about this theme.
