What were you doing in Los Angeles on the night of Aug. 10, 1939? Actuarially speaking, hundreds if not thousands of native Angelenos can still answer that question. Even a 5-year-old on that night would only be 82 today. But how many 5-year-olds in 1939 went to art openings? It’s just possible, then, that no one now alive visited a modest but elegant L.A. art gallery under a candy factory for the unveiling of the most important painting of the 20th century, Picasso’s “Guernica.” What on earth was Picasso’s antiwar masterpiece doing midway between Bullock’s Wilshire and Lafayette Park, its paint only two years dry?

At the time, I was winding down my tenure as director of National Reading Initiatives for the National Endowment for the Arts. Loafers on the desk and the Post in my lap, I felt like Spade in Dashiell Hammett’s “Maltese Falcon” — a book I’d been evangelizing around American cities and towns encouraging my countrymen to read. There was a new NEA chair in town, and literature seemed to rank pretty low among his priorities. On my watch, the writing had always mattered most. Now the writing wasn’t just off the agenda, it was on the wall. I picked up on the first ring. Seven floors down, I heard the security guard hand off the phone. In a papery brogue that sounded two weeks, tops, out of Dublin Harbor, a man’s voice said — actually said — “I t’ink I’d like to
