This is my stamps collection about Mathematics, for which I am much refereed by the website "History of Mathematics" of the University of St. Andrew and the Stanley Gibbons stamp catalogue. For some souvenir sheets, I use the numbers of Scott's. The stamps are arranged by alphabetical order of mathematicians' names below.
