Donald Trump quietly inked a book deal a few months ago, but not to write a memoir about his tumultuous time in office like so many previous presidents opt to do. Instead, the former President has decided to release a coffee table book detailing his presidency. While the book initially went unnoticed by the media, it has quietly been making the former president a fortune.

The book, Our Journey Together, is a work of various pictures detailing the four-year Trump presidency, with each photograph captioned by the ex-commander-in-chief himself.

CNN reports that the coffee table book retails for around $75, or $230 if you want the tome signed.

Sales of the book have reportedly grossed $20 million since the initial run of 200,000 copies went on sale in late November. While Trump is certainly racking up a fortune from the sales of the book, a source also reported that the former president pocketed a multi-million dollar advance.

Demand for the book is reportedly so high that the publisher can’t keep up.

"We still can't keep up with the customers," said Sergio Gor, who founded Winning Team Publish to publish the book. Gor says that he sold all 200,000 copies from the initial run and has requested 300,000 additional copies.

Gor argues that the appeal of the book stems from Trump's loyal fan base who are “hungry for more of the signature firebrand former President,” and the book is “pure Trump” according to Gor. Instead of offering insight into his decision king as the leader of the free world, the book offers commentary from Trump on how he interpreted each of the scenes in the book.

"Attempting to listen to crazy Nancy Pelosi in the Oval Office, such natural disagreement," he commented next to one of the photographs.

Next to another photograph, Trump declared: "Mark Zuckerberg would come to the White House and kiss my ass. His censorship is terrible for America. His 'campaign contributions' even worse."

The book may be sold out, you can still find copies on Amazon and eBay, but expect to pay a premium. A signed copy of Our Journey Together marked as a collectible is selling for $1,749 on Amazon. Copies on eBay are going for $950 all the way up to $1,300.
