After having completed collection of Special Cover bureaus of North, South, East and West, I now start my journey of North East. It is considered to be the toughest leg of the journey. But I feel that more the challenges, journey becomes more adventurous n interesting. Same thing happened with me. Getting Guwahati Post Mark was not a problem as one of my Philatelic friend helped me in getting me and same thing happened in case of Shillong. That is why the cancellation is very clear and bold because philately background came handy and helpful.
But getting cancellation from Shillong GPO was delayed as cancellation design was not received in time. It was received at the Bureau after much follow up by the Bureau.
