[caption id="attachment_34875" align="alignright" width="220" caption="Photo: Ryan Collerd"][/caption] The Raab Collection has a lot in common with other family businesses: a dad (Steven Raab) who founded it, a mom (Susan) who helps run it, two sons who embarked on other careers after college (Jonas, journalism, and Nathan, politics) before returning to the fold. But instead of dealing in widgets or pool maintenance, the Raabs are, as Jonas says, “custodians of history”—buyers and sellers of rare autographs and artifacts. Name an important one that’s come up for sale in the past 20 years—a letter from Susan B. Anthony decrying the treatment of women as “pets,” even the original copy of the Kennedy Assassination Air Force One tape—and it’s likely to have passed through Raab hands. Steven, 64, was bitten by the bug as a boy, after he was given a comic book about Abraham Lincoln and began collecting Civil War memorabilia. He became a lawyer, but he never stopped collecting, and eventually decided to make the hobby his lifework. “Collectors are people who care about history and aren’t content to just read about it,” Nathan says. “They get a special thrill when holding something Lincoln touched.”
