The Straits Times, 1961 - back when one looked through the newspapers for new pen friends to reach out and brighten up one’s social life!
Some things I noticed: 1. The teens were from both Singapore and Malaysia.
2. Common hobbies at the time included stamps, listening to the radio / Rediffusion, swimming, and badminton.
3. These teens would be in their 70s today - if they are still alive.
