Great pics, Michael.
Do I see a pro laying up on #16 at Cypress during the Crosby? There are still people on the green! Or might that be an amateur? Was the Crosby Clambake a pro-am back in the day, too?
The desolation of Pasa before (additional) trees & housing is amazing.
Spyglass isn't THAT old, but b&w pics can make it look so.
The Augusta aerial seems to be pre-RTJ. The new version of #16 isn't there.
Is that ugly-looking retention(?) pond still there at Merion? EDIT: Answered my own question....yes, it's still there, and those saplings around it in the old pic are now big & probably hide it from view.
