It shows several aspects of the Stara Planina Mountain, or if Translated, the Old Mountain. It is a mountain range in the eastern part of the Balkan Peninsula, on the border between Bulgaria and Serbia. On the top picture you can see Midžor, the highest peak of the mountain at 2169 m while on the bottom pictures you have the waterfalls near Kaina, then the city of Knjaževac and the Denseflower Mullein (Verbascum Densiforum).

the stamp is a very cute one, issued in 2008 in a set of two, depicting Children's Folk Costumes.
