The first cover, official mail from Calcutta to New Delhi, still carries British India's official franking "GRI" and was mailed on the 15th.  It carries the special slogan mark in English and Hindi.  The English slogan reads "COMMUNAL HARMONY WILL SAVE GANDHIJI". The Hindi slogan more emphatically states that "IT IS ONLY THROUGH COMMUNAL UNITY THAT GANDHIJI CAN SURVIVE".  Delivery markings on the back indicate that it arrived in Delhi three days later, the day Gandhi ended his last fast.
