The six-month-old Prince was carried by his mother Princess Diana off a plane at Aberdeen Airport in March that year - wearing a cream outfit that featured a bobble hat.
The tribute by the Duke and Duchess of Sussex didn't go unnoticed by royal fans, who according to the Daily Mail, said it brought back "great memories" of Prince Harry as a child.
The publication reported that one observer wrote, "'Love when they channel past looks!" while others noted the striking resemblance the father and son shared.
"So alike in these pics!" said one fan, followed by another who wrote "Archie is 100% his father."

According to the Daily Mail, the royal family - who took a British Airways overnight flight from London - arrived 40 minutes late into Cape Town this morning.
They are embarking on a 10-day tour of South Africa (marking Archie's first official tour and Meghan's first time touring South Africa).
For their first day, the Duke and Duchess visited the Nyanga township to take a workshop run by Justice Desk, which teaches children about their rights, self-awareness and safety (baby Archiewas left with a nanny for the visit).
The pair were given a vibrant welcome from well-wishers, sharing hugs with children and dancing to music before they entered the Nyanga Methodist Church.
The family will also tour the District Six Museum later to learn about the history of Cape Town and will meet former residents.
