This photo belongs to my collection of diaslides which consists on one hand of diaslides which were taken by my father in the 60s and 70s of the last century, mostly as we were on vacation, On the other hand my deceased husband used to use diaslides in the 70s and 80s of the last century; these were the days of the diaslide before digital cameras appeared.
