Godrej archives and museum

One of Professor Tumbe's favourite hidden gems in Mumbai is a piece of Indian electoral history being showcased at the Godrej archives and museum - a ballot box from the country's first ever general elections in 1952. The steel box on display at the exhibition gallery is among nearly 13 lakh ballot boxes that were supplied by Godrej & Boyce for the historic debut of Indian elections. The box has a unique locking system that could only be opened by breaking a pre-impressed insignia, eliminating the need for an external lock. The boxes were tamper-proof, rat-proof and provided at the grand sum of R5 each.
