It can be tough going back to school after the holidays, but the teachers and pupils at a primary school in Bristol got a nice surprise on their first day back after a half term break.   For painted on one of the walls of Bridge Farm Primary was a mural by none other than the mysterious street artist affectionately known as Banksy.  It turns out the school had recenty named one of their buildings after the famous artist and the piece of art was his way of saying thanks.  In a letter that was found near the artwork, Banksy wrote “it’s always easier to get forgiveness than permission”.  Well he should know more than most.  Despite Banksy’s paintings and murals being highly sought after with many fetching eye-watering sums when they come up for sale, Head teacher Geoff Mason said the mural is “inspirational and aspirational” for his pupils and that there are “no plans to sell it”.  Don’t you mean ‘no plans to Banksy it’ sir?
