A large, mounted and autographed, photo on a 50 cm by 75 cm display board. The photo was taken at the start-up of the 25 MW NDP reactor at Rolphton, ON in 1962. The autographs added on the display board were added at a later date, probably on the occasion of the gathering of personnel for 20th anniversary photo displayed in Artifact 2018-007. The second photo has been added here to assist in the identification of the participants.
