I have recently spent a lot of time perusing biker imagery and one stand out photographer seems to be lacking in much of a bio or obit. His name is Pete Chiodo. I understand he has passed. His "Cindy" spread from Oct 1976, Easy Rider, is so iconic that it pops up immediately on many biker imagery searches. I would approach his heirs about prints of his work but searches have been dead ending. I also have a query in to Easy Rider.
