Back in Mumbai... and am very impressed with the Mumbaiya use of space. It's like the traditional reason why Mallus don't do well at football - give them a corner and they open up a tea shop! Give the Mumbaikar some space, and they'll squeeze it for their money's worth. Take this example:

This is an ad overlooking Mumbai's very busy Kemps Corner flyover. It's a brilliant spot to put it at, given the traffic that's going to see this at eye level. What's even cuter is the way this space got created. Behind the ad is a building that's being renovated. They've screened the renovation from the general public and used that space to put up an ad... in what must be Mumbai's most expensive ad spot. Outstanding. Trust the Mumbaikar to put his space to good use!
