375rd Heinrich Köhler auction - Day 1

4 sk. orange-brown, a previously used copy with clear marks of circle cancellation, used a second time with clear numeral "51" on lettersheet with adjacent clear blue "ODENSE 9/3" to Bogense with arrival mark of the same day. A fine letter, believed to be the only surviving example of such postal fraud with this stamp. Certificate Vagn Jensen (1998)
