Many thanks to Vural Oguz for this wonderful cover posted from Geuensee, Switzerland!
The boy scout stamp belongs to a group of six postage stamps (SC#422-27) issued in 1963 with themes such as Scout, Red Cross and Freedom from Hunger.
The stamp in the middle was issued on 5th May 2011 to celebrate Switzerland's part in the Venice Biennale, an international art exhibition held every two years.
This Swiss stamp is one of the most unlikely pieces of art designed by Swiss-born, Paris based artist, Thomas Hirschhorn who is known for his larger than life room-size installations. In designing this stamp as a piece of torn cardboard, Hirschhorn drew inspiration from his earlier works: as an unknown artist in the 1980s, he wrote on cardboard signs and placed them in house doorways or under windscreen wipers.
Last but not least, we have a lovely bee stamp named "Honey Bee" which was released on 3rd March 2011.
