Hello Filip,

The Record Group at the National Archives for the Office of War Information is 208:

https://catalog.archives.gov/id/535 <https://catalog.archives.gov/id/535>

There is a large collection of wartime broadcasts and recordings that is mostly not included in the online database:

https://catalog.archives.gov/id/653144 <https://catalog.archives.gov/id/653144>


The records of the United States Information Agency would also be worth looking at since recordings from World War 2 are in there, too.  That is Record Group 306.

https://catalog.archives.gov/id/622 <https://catalog.archives.gov/id/622>

Check with the Roosevelt and Truman Presidential Libraries as well since there would have been communications between the OWI and the White House.


Good luck.

Michael
