Coover

“It’s that next spin,” said Mike Coover, 35, a plumber at the Tropicana who was gambling at Resorts and said he smoked about a pack of cigarettes a day.

But such tricks have also yielded successful results, including Padgett Powell’s nearly perfect 2009 novel, “The Interrogative Mood,” composed entirely of questions, or Robert Coover’s 1981 story collection “Spanking the Maid,” which retold the same scene over and over again — each time in a slightly new way.

Christopher Coover, 72, an expert on rare books and manuscripts at Christie’s auction house, where he oversaw the authentication, appraisal and sale of documents ranging from the original texts of Jack Kerouac’s “On the Road” to George Washington’s annotated copy of the Constitution, died in Livingston, New Jersey, on April 3.

Coover appeared on the PBS program “Antiques Roadshow,” and assisted in the sale of Leonardo da Vinci’s “Hammer Codex” to Bill Gates for a record $30.2 million in 1994.

In addition to his son, he is survived by his wife, Lois Adams; a daughter, Chloe; and two sisters, Mauri and Regan Coover.
