this is the first picture of the abum that I recognize for sure: it's central Goldberg Group of Hohe Tauern with Hocharn, Sonnblick and Schareck. The valley is Moelltal near Heiligenblut. Großglockner summit can be seen on the bottom on the left.
Thanks again for all answers. I just have a little doubt for Sonnblick, they are 2
it's the correct one!
