Calcutta flag
The Calcutta flag was one of the first unofficial flags of India. It was designed by Sachindra Prasad Bose and Hemchandra Kanungo and unfurled on 7 August 1906 at Parsi Bagan Square, Calcutta.
The flag had three horizontal bands of equal width with the top being orange, the centre yellow and the bottom green in colour. It had eight half-opened lotus flowers on the top stripe representing the eight provinces of India and a picture of the sun and a crescent moon on the bottom stripe. वन्दे मातरम् was inscribed in the center in Devanagari.
