Some harsh, decades-old criticism from Harper Lee about the Trump Taj Mahal in Atlantic City is getting fresh attention, thanks to an auction and the presidential race.

Twenty-nine letters written by the late To Kill a Mockingbird author are up for auction from the Los Angeles-based Nate D. Sanders Auctions.

In one, the acclaimed writer has stinging words for the Boardwalk hotel-casino after a visit in August 1990, four months after it opened.

"The last set of Visitors departed today: the worst punishment God can devise for this sinner is to make her spirit reside eternally at the Trump Taj Mahal in Atlantic City," Lee wrote to friend Doris Leapard in the typewritten letter, dated Aug. 25, 1990.

Lee had apparently gone to the New Jersey resort with her guests. The letter was postmarked from New York City and listed her apartment there as the return address.

The hotel is now owned by billionaire investor Carl Icahn, though it still bears the name of Republican presidential frontrunner Donald Trump.

The letter was listed with $750 minimum bid. The auction runs through Thursday, and the top bid was $1,209 as of Monday afternoon.

Lee died earlier this year at age 89, less than a year after the controversial release of Go Set a Watchman.
