As Bombay transformed into Mumbai, so much has changed over time. We have been fascinated by how Mumbai's look has evolved over the years. We did a series on postcards from Bombay to Mumbai where we looked at historic postcards of familiar sights in Mumbai and revisited them to capture how they appear today. This weekend we put all those together to give you a glimpse of how oiur city has changed in a fun video. Tell us what you think of it!
