"Footpost letter sent within Copenhagen on 9 August 1820. A new type IV footpost cancellation was put into use in 1820 which had two large capital letters "F.P." within a circular ring. This cancellation stamp relieved both types II and III as the procedure of stamping unpaid letters with a red cancellation was stopped. Because of this, letters in 1820 often had a manuscript "frit" or "betalt" - meaning paid. The footpost office also had a framed "BETALT" in Gothic letters. Only recorded "BETALT" footpost cancellation"
