In 1964 Switzerland held a national exposition. The Swiss like expositions - they have one every 25 years; you can almost set your watch by them. This one was was known colloquially as Expo 64 and was hosted by Lausanne, situated on the Lake Geneva shoreline. Amongst the myriad of attractions were the Spiral Tower and the Monorail - which amazingly survive to this day. However, looking at the monorail it was no match for the one at Butlins - both of a similar vintage.
One of the many Kodachrome slides in my collection is this one dated September 1964 - written on the back is LAUSANNE EXPO. 1964. Researching what was on display at the time I think this photograph may have been taken in the L'art de Vivre (Art of Life) section. It's a personal favourite of mine.
