Hungarian mathematician János Bolyai

Comment: "The picture of him is taken from a stamp issued by the Hungarian Post Office to celebrate the centenary of his death. It is not believed to be authentic and no authentic picture exists." cited from J J O'Connor, E F Robertson: János Bolyai, The MacTutor History of Mathematics archive, March 2004

The picture is from [1]. The "Copyright information" at the bottom of the page says: "We believe that most of the images are in the public domain" which is good enough for me.
