I know that story. The graffiti in question was found at Verdun, France, and here is what it said:
“Austin White - Chicago, Ill. - 1918
Austin White - Chicago, Ill. - 1945
This is the last time I want to write my name here.”
Thanks! I was sure I’d heard it from you, but my memory isn’t always a hundred percent.
