Local letter from Fyns Stiftamtsstue dated 10 July 1852 to Odense. Postage paid with 4 RBS Thiele I (envelope folded through stamp), tied and cancelled with what I believe what has happened, is that the clerk has taken the cover, flipped it over and then pressed the corner with the stamp onto the ink pad. I have never seen similar way of cancelling in the past. A most unusual method of cancellation.
