Wall chalking is illegal still I can see unethical and disgusting advertisements on walls which are destroying the beauty of city and increasing visual pollution. People are running their businesses through wall chalking .

This unsophisticated act should be bunged in order to make our city spotless and more attractive. I want to draw the attention of concerned authorities and request them to blank out the entire walls of the city which are chalked as soon as possible.
