Thank you, David, for sharing this lovely moment in time with your mother and father--they look relaxed and happy aboard the Windsor Castle! I looked up information about this ship, since I'd previously not heard anything about it, but it had such an impressive name, and I found out it was the largest passenger and cargo liner operated by the Union-Castle Line on its Cape Mail service between the U.K. and South Africa. It was still fairly new at the time this photo was taken in 1962, as it was completed in 1960.

Thank you so very much for sharing this!
