This is a real philatelic curiosity. It was made with offset, UV and screen-printing using OEI inks, which was used for the first time in Hungarian stamp printing, it was printed on protected paper and has a hologram on it.
By placing the miniature sheet in UV light the black serial number fluoresces green, along the stamp perforation the text 'Jeles magyar matematikusok' (outstanding Hungarian mathematicians) can be read, as can the names of 57 outstanding Hungarian mathematicians.)
The names are:
