In the 1990s, Lee bought two pages of Jack Kirby concept art, which Kirby had created for a film adaptation of Roger Zelazny's novel "Lord of Light", as part of the cover story to smuggle Americans out of Iran during the 1980 hostage crisis. Lee purchased the art at a Sotheby's auction via Barry Geller, the producer of the faux film, who was selling it to help pay for his child's college tuition. The CIA operation that rescued the Americans remained classified for another 17 years, and thus Lee had no idea of the pages' historical significance, nor did Geller know their true monetary value when he sold them to help pay his son's college tuition (with Kirby's permission). Both Lee and Geller learned of the true story behind the art years later with the rest of the public. In August 2013, four of Lee's children were headed for college, and he and Carla decided to auction off the art through Heritage Auctions in order to pay for their education.
