^Here's the entire relevant section copied and pasted. I'm sure the answer is in there somewhere but I don't know which one(s) speak most directly to it. My eyes were starting to cross reading the PDF:
Some regulation sections correspond with the zoning reform of 1961. The MetLife (Pan Am) Building opened in 1959 with two colossal PAN AM wordmarks facing north and south and two large globe logomarks on the east and west. I don't know if the 1961 rewrite forbid such signage or not as 1 Penn Plaza came after with it's large stylized 1 sign in 1972.
