Italin post issued a stamp to celebrate the 150th anniversary of foundation of Club Alpino Italiano (Italian Alpine Club).
The Club Alpino Italiano is the senior Italian alpine club which stages climbing competitions, operates alpine huts, marks and maintains paths, and is active in protecting the Alpine environment. It was founded in Turin in 1863 by the then finance minister Quintino Sella.
After First World War and the annexation of Trento and Trieste to Italy, it absorbed the "Societa degli Alpinisti Tridentini" and the "Societa Alpina delle Giulie".
Its most popular achievement is the 1954 first ascension on K2.
The stamp features a vintage Italian Alpine Club poster, featuring a mountaineer observing the landscape through a telescope; at the top the coat of arms of the Club is illustrated.
