A few years ago, someone paid $448,125 for a single page from Frank Miller’s 1986 edition of “Batman: The Dark Knight Returns,” making it the single most valuable piece of American comic art ever sold. Atlanta lawyer Benno Rothschild, a partner at Hartman Simons & Wood, owns another page from that same printing.

Like Bruce Wayne, Rothschild leads something of a double life. In his day job, Rothschild is a commercial real estate lawyer with a focus on the development and leasing of outlet shopping centers. But he’s been an avid collector of comic art since he was 16, acquiring his first piece for just $150.

“If you had $100,000 in the mid-1980s, you could build a world-class collection of comic art. You could own things that would be like owning the Louvre of comic art,” he says. “Now if you want to do that, you’d have to have $10 million.”

We recently visited Rothschild in his office for a tour of his collection, from his oldest piece to his most expensive.
