Here is Switzerland's February 12, 1998 90 centimes stamp (Sc #1025) publicizing the candidacy of Sion to host the 2006 Winter Olympic Games. Sion (pop. 35,000) is a town in southwestern Switzerland.
The central panel of the stamp shows a collection of 33 tiny images, mostly relating to winter sports and wildlife, to symbolize activities available around Sion. The rabbit, shown in the close-up pic, is approximately 1.75mm x 2mm in size.
