President Trump may be known for spewing his own version of “fake news” with his many statements and tweets but you would think he’d avoid “alternative facts” when it comes to tweeting out a love note to his wife to celebrate her 47th birthday.

Of course, the tweet the president sent out to First Lady Melania Trump wasn’t the most romantic message for one spouse to send to another: “Happy birthday to our First Lady, Melania!”

Then again, the first couple don’t get much press these days for having a warm, happy relationship.But the state of the president and first lady’s union wasn’t the topic of conversation on Twitter following the @realDonaldrump tweet.

Instead, Twitter users were having fun with the fact that the president — or someone in the White House communications office — mucked up in the graphics department, Mashable writer M.J. Franklin observes.

The flag depicted in the tweet only has 39 stars.

Writers with the Washington Post, Huffington Post and other sites the president labels “fake news” were among those daring to correct the president on his bit of “fake news,” Franklin discovered.

There are only 39 stars on that flag, sir. https://t.co/KATgoLIQUv — Dan Zak (@MrDanZak) April 27, 2017

This is so weird: The American flag on @FLOTUS Melania Trump's birthday card only has 39 stars.

Others joked about the status of the 11 states that don’t have stars represented in the flag Trump tweeted out:

MSNBC’s Chris Hayes pointed out that Trump also shared the flag at the end of the video welcoming freed Egyptian American Aya Hijazi who was imprisoned in Cairo. Hayes also wondered if someone in the White House graphics operation has a 39-star flag saved on their computer and pulls it out every time the president needs a flag image.

Franklin then shares what other Twitter users uncovered: that there was never any official 39-star flag.

The design was created in 1889 when flag makers were anticipating the addition of the Dakotas to the United states, they say.

Flag makers incorrectly assumed that what we know as North Dakota and South Dakota would be admitted to the US as only one state, not two. As the New York Times said, the 39-star flag was instantly obsolete on July 4, 1890, when five states were added to the Union.

The 39-star flag also never became an official U.S. flag, though it has become a collector’s item, the Times said.
