An exhibition has opened in Moscow showing prints of nude studies from the 1940s which have been defaced by rude comments, allegedly by former Soviet leader Joseph Stalin.
The note beside this naked man reads: "One thinking fool is worse than 10 enemies. J. Stalin" (Photo by yustas, a member of the Live_report community - a bbcrussian.com-livejournal project).
Another reads: "Why are you so thin, Mikhail Ivanovich? Do some work. Onanism is not work. Try Marxism!" (Photo by yustas, a member of the Live_report community - a bbcrussian.com-livejournal project).
A number of the jottings are signed "J. Stalin", in Russia's cyrillic alphabet.
Organisers claim the jottings - some of which refer to Stalin's Bolshevik party members - have been authenticated by an interior ministry expert. But it is not clear how or why Stalin might have made them.
Some suggests the comments are the musings of a lonely man. Others say they indicate homosexual tendencies of the late dictator, although psychologists have dismissed this.
What are these?
