PCy Twombly

I was just checking Cy Twombly’s childhood address yesterday by looking up his 1946 draft card on Familysearch, as one does, and saw his signature: Edwin PCy Twombly. Did the high school senior standing in front of Mrs Beatrice McKenny Garth of the Rockbridge County Draft Board start to sign his government name, and then switch to Cy? Except Cy Twombly fits on the line. Did he sign his name, and Mrs Garth was like, “I am not writing this all out again, young man. Fix it.”? The real thing I wonder is if Twombly hadn’t developed an art practice so infused by handwriting and line, and a writing style so intrinsic to that practice that his notes and letters often came to stand on their own as artistic objects, would I have ever even noticed?
