Chris, the aerial that he would have access to, is he does, is one from the late 30's, which would be a good number of years after the course was designed by Emmet and after alterations had already begun...
Sad to say, whether you see a lot of Emmet in the greens or not, today's Eisenhower Red course has very little of the original Emmet course left to it.
There are features on individual holes that remain, but only a couple, if that many, remain as they were built.
That is a shame for he was and remains an under-appreciated architect.
