Heparin T-shirt

This lovely stamp was issued by Aland in 1994 and celebrates J. Erik Jorpes a pioneer in the identification and clinical applications of heparin.  Swedish biochemist J. Erik Jorpes is credited with identifying the chemical structure of heparin (a potent blood thinner) and promoting its use as standard therapy for many common disorders. 

The Åland Islands or Åland is a region of Finland that consists of an archipelago lying at the entrance to the Gulf of Bothnia in the Baltic Sea. It is autonomous and is the only monolingually Swedish-speaking region in Finland.

Åland's autonomous status means that those provincial powers normally exercised by representatives of the central Finnish government are largely exercised by its own government, and thus Aland can issued its own stamps.
