My Collections


     Welcome to and thank you for visiting my collection webpage! Apart from a particular interest for Vietnamese mint stamps, I love collecting postal documents about Vietnam, about Hans Christian Andersen, about Vincent van Gogh, and, above all, about Mathematics. Recently, I have also moved on to banknotes featuring mathematicians and physicists.

     Hope you would enjoy your time here awhile. If you come up with any suggestions, please let me know.
