Typeface used on 1953 Federal Government logo.

Just joined this site, and was hoping someone might be able to help me identify the typeface used in this logo. The design was created in 1953 for the Mutual Security Agency, then part of the US State Department. The logo was then adopted by MSA's successor organization: the US Agency for International Development.

I'm also very interested in identifying what "school of art" the overall design could be tied to. I'm not an art historian, but I'd love to get one to weigh in.

Thanks very much!
