Ben -
The overlay is terrific. It looks like the right side of the aerial was cropped. It cuts out some greens and tees on the right side of the picture that would be interesting to see. Do you have an overlay for the full aerial?
Duncan's GD article gets a couple of things wrong. Ross did not "build" EL in 1913. The current course was routed by George Adair with help from H. H. Barker in 1913. We know that because Adair presented a rerouting of the old Bendelow course to the board of the Atlanta Athletic Club in late 1912 (see The American Golfer). The Adair routing is, essentially, the current routing of the course. Ross did a "sophisticated bunker plan" at both EL and nearby Druid Hills later in 1913. There is no record of Ross's bunker plan, photographic or otherwise. Nothing at the Tufts Archive on it.
If design attribution follows the person responsible for a course's routing, George Adair has been badly neglected. And not just with respect to EL. Adair was the father of golf in the SE. He promoted tournaments, chaperoned young Bobby and his son Perry on trips to tournaments, helped layout a number of courses in the SE (usually with the help of Barker and Stewart Maiden), was a friend of CBM, Travis and the Tufts, and a force at the Atlanta AC. An important, beloved figure Adair died in 1921 in early middle age and has been largely forgotten. (Someone who did not forget Adair was O.B. Keeler. But that's another story.)
Another minor correction to the GD piece: EL No. 2 was built by Ross in 1928. We have the Ross plans, newspaper accounts, etc. It was considered by everyone I have talked to who played No. 2 as the better of the two courses. Charlie Harrison, the best amateur (after Jones) from EL (who won club championships at EL into his 80's) loved the No. 2 course. No. 2 ceased to exist not in the 60's but in the mid 70's, though I would guess that its maintenance had fallen off by the time of its closure. A short nine hole course was built on a portion of the old No.2., finished in the early 2000's, as I recall.
I think Andrew Green and Chad Parker have the right take on EL. Their goal seems to be simply to make EL a better course and to play down suggestions that it is a Ross restoration. Any claim that it is a restoration has the insurmountable problem of defining what of Ross they want to restore at EL. About that virtually nothing is known.
A comment on the 1949 aerial. Note what looks like an old green with a fronting bunker to the right of and midway along the 17th fw. That might be the remnant of the old green when the 17th played as a long par 3. You can also see traces of the old double, summer/winter greens at several locations. Double greens were used as late as the mid-1930's, maybe longer.
