I believe this is the Wilmington, Delaware assembly plant judging by the convertible that employee Robert Hall is looking at. My brother ordered a new convertible that year and as I recall they were only assembled in the Wilmington plant. Very rare was the instance of the line shutting down for a moment of silence. I can personally think of only one time in my years at Buick. It was for an employee killed in the factory. The date of this photo was May 16, 1970. Reuther died May 9th.
