Today is World Post Day. 9th October is the anniversary of the Universal Postal Union (UPU), which started in 1874 in Switzerland. The UPU signified the start of the global communications revolution, which introduced the ability to write to people all around the world. World Post Day was launched in 1969, to highlight the importance of the postal service, where the 9th of October was first declared as a day of celebration at the UPU Congress in Tokyo that year. The proposal was made by Anand Mohan Narula, a member of the Indian delegation. As we get nostalgic about a time when the world was devoid of email exchanges and WhatsApp messages, I commemorated the day by sending out these postcards for Postcrossing – a postcard exchange community I have been part of since the last four years.
