A Banksy in the bank.
This print (Kids on guns) was bought 3 years ago in a Brighton art store for £250, the other day it was sold at Sutherbys for around £150,000.
I know someone who has this print (Pulp Fiction) they bought from Santa's Ghetto in London about 5 years ago for £50, god knows what's its worth now! Any one have any ideas or want to re-mortgage their house for it?
