David Letterman is not only an author of “This Land Was Made for You and Me (but Mostly Me),” a new humor book he created with Bruce McCall. He is also a target of its pointed populist satire, and he knows it.

“We’re at the top of the list of dopes with too much money, who go to Montana and buy up land,” Mr. Letterman, the longtime host of CBS’s “Late Show,” said recently, referring to himself and the few people who can call themselves his economic peers. “But there is a different view of it, hopefully, that some of us have not fallen prey to.”

“This Land,” which Blue Rider Press will release on Tuesday, and which bears the mocking subtitle “Billionaires in the Wild,” contains dozens of Mr. McCall’s quietly absurdist paintings, depicting nonexistent monuments to extravagant modern-day wealth: a hunting lodge with an indoor airport, a ski chalet hurtling down a snow-covered mountain on a set of giant metal runners.

The art is accompanied by descriptions of fictional moguls and their irresponsible indulgences, like the “pharmaceutical patent fixer” who painted an entire river to match the clothing worn by his new wife, “the only former groin model to market her own line of eco-friendly sex toys.”
