Mrs. Clinton also shared the post on Twitter and included a link for fans of her husband to sign a happy birthday e-card


Hillary Clinton is throwing it way, way back to celebrate President Bill Clinton’s birthday.

The former first lady and secretary of state, 71, shared a special birthday wish for her husband on social media Monday to mark his 73rd year — and she reached deep into the family vault to do so.

“Happy birthday, Bill! 🎂” she captioned her post: a black-and-white shot of a young Clinton wearing a romper and sandals.

In the photo, he stands next to an unusually designed birthday cake topped with three candles that appears to be precariously stacked atop an ottoman. A spokesman tells PEOPLE that he was 3 years old in the photo — as the candles suggest — and that it was taken in an Olan Mills studio while he was living with his grandparents in Hope, Arkansas.

(The cake is believed to be a prop, according to the spokesman.)

For his birthday on Monday, Clinton spent the day with friends and family with a cookout at his New York home planned for Monday night, the spokesman says.

Mrs. Clinton, who married him in 1975, also shared the post on Twitter and included a link for fans of her husband to sign a happy birthday e-card.

One of those fans was Barbra Streisand, who shared a birthday note of her own to the former president and humanitarian as well as the contents of the letter she wrote him.

“I wanted to share with you the note that I just sent @BillClinton to thank him for all he has done for our country and continues to do through the amazing work of the Clinton Foundation. Please, join me in wishing him a happy birthday!” Streisand wrote on Twitter.

Clinton established his family’s eponymous foundation after leaving the White House with the goals of improving “global health and wellness, increasing opportunity for girls and women, reducing childhood obesity, creating economic opportunity and growth, and helping communities address the effects of climate change.”

Mrs. Clinton, meanwhile, has used throwbacks before to mark her husband’s birthday.

In 2015, she celebrated him turning 69 with a black-and-white photo of the two looking lovingly into each others’ eyes early in their romance.
