Last week, street artist Banksy, disguised as a London Underground cleaner, painted an excellent artwork inside a train car urging people to wear face coverings due to COVID-19. Video below. Turns out though, an actual cleaning crew wiped away the work shortly after it was created. From CNN:
The work was removed "some days ago" because it was in violation of [Transport for London]'s "strict anti-graffiti policy," a spokesperson for the transportation agency said in a statement.
Even though it was erased, the spokesperson said that TfL appreciated "the sentiment of encouraging people to wear face coverings" and that it would like to "offer Banksy the chance to do a new version of his message for our customers in a suitable location."
