A print of the Chi-Rho-Siete from the Book of Kells. Actual copy is in the Swiss National Museum in Zurich. Bought the postcard from the Museum's gift store.
This is Mount Eiger, which is situated on the Bernese Alps. The image depicts the famous Nordwand (North Wall), where at least sixty-four climbers have died since 1935. Ironically, it's nickname is Mordwand (Murderous Wall).
