So interesting to see this again! I'm Danish and lived not far from Helsingør across the water as a kid and young man... I remember going with my parents on the ferry to Helsingborg because we could buy cheap coffee and salami in Sweden, compared to Danish prices... this was around 1970-75.
Nice photos and story!
How cool! I was amazed there was so much ferry traffic between Sweden and Denmark but later saw how entire trains are shared across the border. Thank you!
