The Swiss stamps you are asking about are part of the long-running annual Pro Juventute semi-postal (charity) series. These issues feature a surtax (the extra amount above the postal value) that goes to the Pro Juventute foundation for the welfare of children and youth in Switzerland.
The issues from 1923 and 1924 shared a common design theme: the Coats of Arms of the Swiss Cantons and the Swiss Confederation.
