Residents of Stourbridge, West Midlands (UK) and surrounding villages were having a pleasant surprise when they took their milk bottles. They would find pictures of animals, often cows or mice, carefully carved onto the glass in astonishing detail.
The artist, called by neighbors as 'bottle Banksy', would take the used milk bottles from doorsteps and then return them after having etched elaborate pictures. The identity of this artist was later known: Charlotte Hughes-Martin (http://www.charlottehughesmartin.com/). The ex-lecturer, who works from a studio in a former glass factory, decorated the used bottles before randomly returning them to the doorsteps. Meet Charlotte's Milk Bottle Art.
