The logo for State Bank of India, India’s largest commercial bank was designed on 01 October 1971. As an initial response to the circle form with an open hole, it looks like a key-hole. But, the real concept behind the design being that the circle encloses a common man inside at its centre. The common man represents the centre of the bank’s business. The circle signifies the service of trust, security and perfection for the common man. Moreover, the slogans With you all the way and The banker to every Indian support the idea of serving the common man as the epicenter of its activities. This logo is a unique example of how to create a quality of a concept with most basic geometric form of design i.e. the circle.
