Course pédestre, journée porte ouverte et stands divers

Saturday 25 October 1969 was 'Open Day' at CERN when CERN staff, their families and friends could tour the site to see the big machines and specially prepared exhibits illustrating the work of the different sections. By the end of the day 2472 visitors had been clocked through the gates. For the first time on an Open Day, there was much to see at the Intersecting Storage Rings.
