Trevor,
Besides just being wonderfully charming vintage photographs, I think those pictures have great value in capturing many of the holes just as trees were starting to encroach a bit on the original fairway widths.
I'm hoping some folks from the club get a look at them, and contrast them to the growth today, which is a bit more pervasive and intrusive.
In any case, thank you very much for sharing these terrific mementos from your grandfather.
They are really a priceless treasure.
