A special set of stamps was issued earlier this year to mark the golden wedding anniversary of the Prince Hans-Adam II and Princess Marie of Liechtenstein. In addition to the actual stamps, a special version featuring gold foil and a small ruby was also issued. Proceeds of the stamps go to the Liechtenstein Red Cross that was headed by the Princess for thirty years between 1985 and 2015. Hereditary Princess Sophie took over the Presidency of the organisation two years ago. It was she who received the first donation earlier this month.
