That big red triangle in the background is a section of the world's biggest wheel of Edam cheese. It'd been wrapped in wax and was ready to be presented as gift to a Chinese diplomat arriving in the USSR.
Unfortunately no-one thought to protect the cheese from an enraged goblin who devoured it whole. They didn't have time to replace it and when the CPC guy arrived with a bronze Lenin bust the size of five Lenins, he got angry that he didn't get anything in return and vowed eternal revenge on the USSR.
This is the real inciting incident of the sino-soviet split and also invention of pogo sticks which the USSR believed could be used to better pursue goblins.
I don't know how the person in the foreground is, perhaps a metaphor for the people whose lives were lost to inter-socialist infighting.
