To provide additional context about “artist interpretation”, this is from the WSJ archive link:

The letter bearing Trump’s name, which was reviewed by the Journal, is bawdy—like others in the album. It contains several lines of typewritten text framed by the outline of a naked woman, which appears to be hand-drawn with a heavy marker. A pair of small arcs denotes the woman’s breasts, and the future president’s signature is a squiggly “Donald” below her waist, mimicking pubic hair.
