Perhaps the man in the middle is either Roger Lapham or Jack Neville.
I think I mentioned it above, but again, to me one of the most interesting aspects of these really beautiful and detailed hole drawings of Pebble Beach in 1929 is not just the drawings but the notation on every one of them---eg "By Joe Mayo and Campbell Puget"
I assume Puget may've been the artist who drew them but what could be the significance of Mayo's name on them? I do know that Joe Mayo was the very good greenkeeper for Morse and PB and maybe Monterrey Peninsula but it is so interesting his name is on those drawings rather than the architect of the time or one of them such as Egan.
Are there any actual architectural drawings for the 1929 remodel of PB, such as construction drawings?
Who knows more about Joe Mayo other than that he was PB's or Morse's really good superintendent?
