Dere Mr President (1972)

Back in the day, there was a trend of publishing "Children's Letters to..." books. "Children's Letters to God" by Stu Hemple was the classic.
So, one of the knock-offs was "Dere Mr. President," which was a collection of letters written to Richard M. Nixon a mere 2 years before he resigned.
The fact that this was "A Production of the United States Information Agency" makes me wonder is this was some sort of propaganda produced to soften Nixon's image. I mean, where and why was this shown?
Enjoy Dick Van Dyke's earnest narration and the groovy art design.
