I like the idea of a newer publication.
Agreed that Dave's site is the "go to" reference in our hobby, but there is something tangible about a book that any website just doesn't have.
It would be a massive undertaking and I can see some squabbling about which bikes to include and which ones were left out... criteria based on subjective condition, perceived rareness, and bias.
Personally, I would exclude all restored bikes, which I appreciate, but a disqualifier if you are aiming at being a reference (if a coffee table book, okay I guess).
I don't have the evolution books, but the examples are mostly from a small collector subset right?
If a book is ever conceived and is moving forward, I would take some good pics and contribute, asking ownership credit only.
