He's the photographer, and for Buddy Holly-files, he's a celeb in his own right. Buddy was famous (while alive) for such a short period time that there were very few pictures taken of him. His wife, Maria, has always liked this picture the most and has used it for all of his promotional materials over the years. This picture was taken just a few days before the concert in Clear Lake Iowa, the place where he died in the airplane clash.
Here's a picture from the concert in conjunction with his star on the walk of fame this week and the release of a fantastic tribute album.
