Flags of Mumbai.
The recently held Bahujan Kranti Morcha was a flag waving show. The theme of the pro-reservation protest was to bring together the various caste and religious groups seeking reservation on one platform. The device to bring them together were the flags with Dalit (Blue), OBC (Yellow), Maratha (Saffron) and Muslim (Green) colours. Shown above is the advertisement for the event that were on hoardings across the city.
Here are a few pictures of the flags before the event at Azad Maidan.
