STAMPS Postage stamps are not merely small piec- es of paper with a printed image and nominal value. With their motifs, a country can pres- ent its natural, cultural and historical heritage and preserve the memory of meritorious indi- viduals, events and important anniversaries. At the Museum of Post and Telecommuni- cations, an out-station of the Technical Muse- um of Slovenia, we hold a rich philatelic col- lection of about 1,500 stamps, first day covers and postal stationery. ANTON PETERLIN, 2012 Picture postcard issued to mark the 100th anniversary of the birth of Slovenian physicist Anton Peterlin. The postcard features his bust, the Jožef Ste- fan Institute of which he was the founder, and a model of a macro-molecule. (S0004576) Special mention should be made of the Verigar issue, the very first Slovenian postage stamps that will go on public display for the first time in the temporary exhibition of the 100th anniversary of their issue, in 2018. We went through our collection to dis- cover who of the scientists presented at the exhibition ‘Knowledge without Frontiers’ de- served public acknowledgement in a stamp form.
