From Dangerous Minds:

But having been around enough older socialists and communists, I do know that the USSR was actually a hot destination for a while, especially for leftists. I even know a couple people whose parents took their honeymoon there! And this was certainly encouraged by Stalin, himself, who established the government-run tourism board with the express purpose of raising the profile of the USSR.

Below, you see Soviet travel brochures from the 1930s. They advertise advanced industrial development, a commitment to the arts, gorgeous cities, and a diverse array of natural beauty. Some of them touch on Socialist Realism, but what strikes me is the diversity of the art, and the visibly ambitious optimism therein.
