Here is an invitation to the International Exhibition, Paris 1937, that the USSR would also use as an international gathering for the 20th anniversary of the USSR.
Below is the Eric Ravilious designed cover for the British version of the guide. There was also a cover in French.
The booklet below is where many of the photographs from this booklet come from. They have simple colour tints.
The booklet is full of interesting photos of the pavilions of each country. What visitors would have found most interesting that in 1937 both the Russian and German powers had key spots and so made towering entrances facing each other.
The front view of the British Pavilion is above and the side view below.
The Finnish Pavilion below was designed by Alvar Aalto.
