The Prince of Wales arrived in India on Saturday for the Commonwealth Games and was immediately greeted with an image from his past that left him a little surprised.
Charles was shown a picture of himself from 30 years ago as he met staff and students from a prestigious institution that is leading the country's technology and engineering research, reports the Daily Mail, London.
He peered at four photographs that showed him with dark hair, slightly trimmer figure and a less lined face and was told they were taken when he visited the educational establishment in 1980.
He told the gathered students and staff from the Indian Institutes of Technology - a group of 15 engineering and technology bodies - that is celebrating its golden anniversary he was amazed at their achievements over the years.
Speaking at a reception held at the British High Commission in Delhi the prince said: 'It is remarkable it's been going 50 years, it will be interesting to see where you all end up - you all make a huge contribution.'
Joking about the black and white pictures, which showed him giving a speech in 1980 and shaking hands with students, he said: 'If you see a photo of yourself after 30 years - it's rather worrying.'
Charles is in India to represent the Queen at tomorrow's opening of the Commonwealth Games, which has been plagued a catalogue of problems.
The latest setback saw officials accused of allowing children to rehearse for the opening ceremony with little food or water, which led to some collapsing, according to reports.
The youngsters spent hours performing routines in blistering temperatures this week with some also complaining about cramped conditions.
Lalit Bhanot, secretary-general of the Games' organising committee told the Hindustan Times: 'Yes, there was a problem but it has been sorted out. There was food but the problem was with the distribution.'

The Duchess of Cornwall is already in India and spent the last few days at an exclusive health centre near Bangalore with family and friends.
The Earl of Wessex, who is vice-patron of the Commonwealth Games Federation, will also attend the opening ceremony and arrived today with the prince by plane from the UK.
During the visit Prince Charles and Camilla will also attend events in the Punjab and Rajasthan.
Some of the themes for the tour have been described by Clarence House as 'bilateral trade and investment promotion, education, military co-operation, protection of the environment and youth entrepreneurship'.
A spokesman added: 'The prince has visited India on many previous occasions and has placed great emphasis on supporting and encouraging the British Indian origin community for more than 30 years, most recently establishing his British Asian Trust in 2007.'
He added: 'At the British Government's request, climate change is at the heart of the programme.'
