W. G. Sebald at 17, a photograph of a photograph

From 8mobili's photostream on Flickr, here's a photograph of W. G. Sebald's 1961 blood donor card, containing a photo of the author as a 17 year-old young man. Since the only familiar images of Sebald show him in the last two decades of his life, there's a slight shock in realizing that he was once this moody-looking Bavarian youth.
