Here is one of the most prized books in my library of mountaineering literature; a signed first edition of The Ascent of Nanda Devi by H W Tilman, in its dust jacket. I bought it on Ebay for about $20 a few years ago.
The book is signed not by Bill Tilman but by Charles Houston, the leader of the successful 1936 expedition. At the time Nanda Devi at 7816m, was the highest mountain that has ever been climbed.
I grew up in the town of naini Tal in the Indian Himalayas within sight of Nanda Devi so this book hold special significance for me. I think I have about 20 books on Nanda Devi.
