Is there any documentation of Joseph Stalin reading 'Animal Farm' by George Orwell?

Stalin was reportedly a voracious reader.

However, there is no evidence that 'Animal Farm' was included in his library.
The following site suggests he did not even read much English language literature without confirming whether or not he even could read English.

[Personal opinion]
'Animal Farm' was published in 1945 at the height of Stalin's power within the USSR (some would say megalomania). Even if he was aware of the book, he might most likely have spurned the literature as just another anti-communist rant and ignored it.
