The piece depicts Oscar Wilde escaping the Reading GAOL prison with his typewriter knot to the bedsheets. Oscar Wilde had been incarcerated in Reading GAOL prison after being convicted of gross indecency in 1895. Wilde was sentenced to two years of forced labour.
The piece has not yet been confirmed by Banksy’s normal channels, but, it seems to be an authentic one.
Maybe Banksy’s next big project is a book?
