Vandalism by Banksy has been defaced just 48 hours after it appeared.
The vandalism, featuring a young girl firing red flowers from a catapult, appeared on the side of a house in Bristol on Thursday.
Banksy confirmed he was behind the vandalism by posting a picture of the work on his Instagram page at midnight on Valentine's Day.
But new vandalism has now been daubed over the vandal's design in bright pink lettering.
