Pamela Anderson recently tweeted an image of a note first lady Melania Trump had sent, thanking the actress and animal activist for sending her a faux-fur coat as a gift.

However, media outlets and other observers quickly turned their attention to the first lady's signature on the letter—specifically, its similarity to the way President Trump signs his name.

As handwriting expert Sheila Kurtz told Yahoo, "Hers looks just like his, which is absolutely amazing."

Both signatures have been described as spiky with thick black lines.

There has been speculation about the unusual likeness, with Uproxx's Kimberly Ricci writing, "Is President Trump answering his wife's letters? Did he sign this letter and keep the coat as a fancy bathrobe? Is he a fan of Baywatch? Lots of questions need to be answered here."

However, the Washington Post reports that the first lady's signature may be the result of an autopen which it describes as "a device often used by public figures to sign letters from senders who couldn't possibly personally John Hancock all their correspondence."

Meanwhile, Kurtz said, "Maybe they brought someone in to show her how to do it or [it's] a stamp, but it is definitely stylized."

Regardless of the method that was used, she interpreted Melania's almost illegible signature style as an indication of a strong desire for privacy.

Handwriting experts have previously analyzed the unique way her husband signs his name. Certified analyst Kathi McKnight told US Weekly that "the razor sharp writing, full of points and wedges, reveals someone whose mind is extremely analytical."

Meanwhile, Tracey Trussell, a U.K.-based expert, is quoted as telling The Independent that "His signature transmits wild ambition, dynamism, bravery and fearlessness...He's hungry for power and has both determination and stubbornness in spades."
