Back In The USSR (For A Holiday)

In one of his 1930's travel books (the title of which escapes me), Richard Halliburton visited the Soviet Union.  I do not remember all the details, but I know he got married and divorced within a few minutes, to and from his tour guide.  This activity, and the rapidity with which it could be accomplished, was apparently a popular tourist attraction.  He also visited a school for young circus performers, and interviewed a soldier who gave an account of the execution of the Romanovs.  According to this article from the May 1934 issue of Harpers Magazine, posted on Modern Mechanix, visiting the USSR as a vacation destination was not as unthinkable idea as it would be a few decades later.
