UNESCO (United Nations Educational, Scientific & Cultural Organisation) was established in 1946. Since then many of its World Heritage Sites have been commemorated on stamps.
At the UNESCO General Conference in Paris, 1968 it was decided that activities would be initiated to commemorate the centenary of the birth of Len in, including the organisation of a symposium on the theme: 'Len in and the development of science, culture and education'.
The symposium was held in Tampere , Finland , from 6 to 10 April 1970 . Tampere was chosen because Len in lived here from 1905 to 1907. The city houses the only Len in Museum outside the former Soviet Union .

One of my favourite Canadian stamps shows the Kluane, Wrangell-St Elias, Glacier Bay and Tatshenshini-Alsek national parks declared a UNESCO World Heritage Site in 1979 for its spectacular glacier and icefield landscapes and for its habitats for grizzly bears, caribou and Dall sheep.
