Sauna postage stamp bookled

The first stamp shows a moment before a sauna. The sun is going down, there's a fresh birch whisk in the bucket on the jetty, and soft towels await the bathers.
The second stamp shows the bathers actually in the sauna, and the third stamp depicts an idyllic shoreline sauna in its natural setting.
The fourth and fifth stamps show sauna atmosphere inside and out: a sauna whisk bathes in the sunlight on a log wall, and inside the sauna the sunshine lights up the bathing place through a window.
The Sauna stamps include microscopic scent capsules. When the stamps are rubbed, the capsules burst and spread a pleasing aroma of birch leaves.
