Lest we forget, today is the centennial of the sinking of the RMS Lusitania. It’s getting some attention online. The latest book about the subject, Dead Wake: The Last Crossing of the Lusitania, came out recently, and I plan to read it in the near future. It’s by Erik Larson, who wrote The Devil in the White City, which is a strong recommendation, so I’m looking forward to it.

One more item from my May Day foray to downtown Chicago: “Batcolumn,” a very tall (101 feet) statue standing in front of the Harold Washington Social Security Administration building at 600 W. Madison St.

The sculpture was erected (and it must have been some job) in 1977, commissioned by the GSA. That reportedly annoyed people who objected to spending public money on making interesting things, but here it is, nearly 40 years later. I don’t know that it’s a favorite bit of public art among Chicagoans — not like the Picasso or the Bean — but everyone’s seen it, and no one seems to object to it any more. I think the government got its money’s worth.

The Swedish-born U.S. sculptor Claes Oldenburg did the work. His specialty: large versions of ordinary objects. While looking at some of his other items on line, one looked familiar right away.

It’s “Typewriter Eraser, Scale X,” which we saw at the National Gallery of Art Sculpture Garden in Washington DC in 2011. Back in 1998, I think, I also saw “Spoonbridge and Cherry” at the Walker Art Center in Minneapolis.
