I have seen only very few photographic images of #Nessmuk, and I've been a fan of his for longer than most. No image I have ever seen of him has been this detailed, not even at The Adirondack Experience (formerly The Adirondack Musuem), which has his canoes (and is definitely worth a visit to Blue Mountain Lake, NY).
This book, by the museum, features one of the only known photographs of Nessmuk.
