"The Watchtower" detailed further expansion in the 1950s and 1960s: "In 1956, a 13-story building was constructed at 77 Sands Street. Then just across the street, another (10-story building) was purchased in 1958. In 1968, an adjoining 11-story new printing factory was completed. Along with the factory at 117 Adams Street, these fill out four city blocks of factories that are all tied together by overhead bridges. Then in November 1969, the Squibb complex located a few blocks away was purchased."
