In summer 2016, Posti and the tabloid paper Ilta-Sanomat collected almost 1,500 sauna photos from their readers. A jury selected four of the photos to be included in the booklet of stamps, as well as one additional sauna-themed photo from the Åland Islands. The booklet of domestic no-value indicator stamps was designed by Klaus Welp. The Sauna stamps are a joint release with Åland Post.
- The atmosphere and closeness of nature in the photos show the Finnish sauna at its best in summer, says Design Manager Tommi Kantola from Posti who acted as the chairman of the jury.
Other members in the jury were graphic designers Jukka Kinanen, Matti Remes and Klaus Welp from the Stamp Art Committee and photographer Pete Aarre-Ahtio from Ilta-Sanomat.
