Can't you just simply feel the breeze and the fresh mountain air?
The card says to show the long tradition of 'blowing horns and flag spinning' .
And this wooden horn is called...well, an Alphorh, of course :)
It consists of a natural wooden horn of conical bore, having a wooden cup-shaped mouthpiece, used by mountain dwellers in Switzerland and elsewhere. Similar wooden horns were used for communication in most mountainous regions of Europe, from French Switzerland to the Carpathians.
The well-known "Ranz des Vaches" is a traditional Swiss melody often heard on the alphorn. The song describes the time of bringing the cows to the high country at cheese making time..sounds hillarious :P
and here it is, so you know what it is about...doesnt sound bad actually :) (ignore the children running around...)
again, a combination of a common and not such a common stamp...the rye stamps from 2008 are more well known..but this other larger stamp was issued in 2011 and is from a set of 3 UNESCO whs stamps, with this one showing Lavaux (or particularly the Lavaux Vineyard Terraces...)
