The "Focus On Switzerland 1975 Landscape Culture History Economy 4 Book Set" is a comprehensive collection of books that delve into various aspects of Swiss culture, history, and economy.

The landscape book has a written note to Astronaut Charles Duke dated July 16, 1976.  I am thinking he was given the gift at the 37th Venice Biennale (swiss pavilion). 

This set includes Letter to Reader and a color map.

The set likely includes a detailed exploration of Switzerland's landscapes, customs, ethnic ties, and economic development during the year 1975. With a focus on Swiss history and cultural significance, this set is a valuable resource for anyone interested in learning more about this European country's past and present.

ALL the books are in great condition.  The outside box has wear (see photos)
