A new photo released by the Carter Centre shows US President Joe Biden and first lady Jill Biden at the Georgia home of former presidential couple Jimmy and Rosalynn Carter.
Mr Biden and the first lady had been in Georgia to attend a rally in Atlanta, where the president outlined his plans to revamp the economy after his first 100 days in office.
Before the rally, the Bidens met the Carters at their residence in the tiny city of Plains, where Mr Carter was born. Though some photos of their meeting outside the home were released, this is the first showing both couples together in an intimate setting.
The new photo has been shared thousands of times on social media, with many expressing their happiness at seeing the two presidential families together.
"America and the world owes a great debt of gratitude to the Carters," said one Facebook user. "A living example of faith and charity. Terrific to see that recognised by the Bidens."
Others have expressed some confusion and amusement over how the camera angle has made the Carters look abnormally small compared to the Bidens.
"I've been staring at this photo for three hours," said one Twitter user. "I've got to go to bed. Back at it tomorrow."
"Are they very small or is this a forced perspective thing like Lord of the Rings?" another user asked.
Mr Carter, a Democrat, served as president from 1977 to 1981.
Mr Carter and Mr Biden have a decades-long alliance, with Mr Biden supporting Mr Carter's bid for president when he was serving as a first-term senator from Delaware.
