The black and white prints of RFE/RL were donated to OSA by the Hoover Institute, California in year 2015. The images are duplicates of those held at Hoover. The originals, and most probably the negatives are with the donor as well. OSA only received the paper prints with captions, and digitized the entire collection in year 2018.
ORIGINAL CAPTION:
Freedom's answer comes from Radio Free Europe which your contribution will help to support through the Crusade for Freedom. Radio Free Europe helps to foster the spirit of resistance among 70 million captives of the Kremlin in Poland, Czechoslovakia, Hungary, Romania and Bulgaria, thus crossing up the Soviets where they are the most vulnerable. Photo shows Radio Free Europe's transmitter at Holzkirchen, Germany. It is 14 times more powerful than any radio transmitter in the United States. (Crusade for Freedom photo)
