Predating 24-hour media coverage and years ahead of Instagram rants and Twitter tizzies, Republican presidential candidate Donald Trump mastered the art of the letter, according to a Thursday piece in the New York Times.

The Times examines letters sent from the desk of The Donald to political adversaries and personal heroes alike, from his time as a New York real estate magnate, through his rise to the Republican Party’s presumptive nominee.

“P.S. You are a loser,” he wrote to movie director Mike Tollin in 2009, pillorying his film about the fall of the United States Football League, and calling the documentary “third rate” and “extremely dishonest.”

Not everything he wrote was negative.

“I adore and love my little darling,” to former wife Ivana. “I truly believe that you are the greatest,” he told her in another.

Framed, hanging and pinned across offices, bedroom walls and desks across the country, the pendulum swings of emotion found in Trump’s letters reflect much of what the electorate has witnessed in the past several months: Trump often enthusiastically declaring his love for supporters and admonishing the “dopes” and “losers” against him in the same breath.

“If I had a secretary to do them (…) they wouldn’t be nearly as effective, they wouldn’t be nearly as sharp,” Trump said of his affinity for old-fashioned pen-and-pad communication.

The Times isn’t the first journalistic endeavor to examine Trump’s correspondence.

In November of last year, journalist Graydon Carter wrote that decades after referring to Trump as a “short-fingered vulgarian” in Spy magazine in the 1980s, the Vanity Fair editor still receives the occasional note from Trump that includes a magazine photo of the billionaire businessman with his fingers circled in gold Sharpie. The handwritten words? “See, not so short!”
