Britsh Museum displays prehistoric supermarket trolley

The British museum has been unknowingly exhibiting work by Banksy, better known as a graffiti artist. The “prehistoric cave-painting” was described as follows:

“This finely preserved example of primitive art dates from the Post-Catatonic era.
The artist responsible is known to have created a substantial body of work across South East of England under the moniker Banksymus Maximus but little else is known about him.
Most art of this type has unfortunately not survived. The majority is destroyed by zealous municipal officials who fail to recognise the artistic merit and historical value of daubing on walls.”
