2 sk. blue with good to large margins, tied by numeral "1" to small local envelope with adjacent blue foot post marking of 15.5.1864. The letter was marked "fr." in the lower left corner, contrary to the postal regulations, therefore charged as an unpaid letter with 3 skilling, with deduction of the adhesive finally charged with "1" skilling in red crayon. The only recorded example. Certificate Nielsen (2003)
Provenance: Peer Lorentzen (Hoiland auction, 2003), Ole Steen Jacobsen (Bruun Rasmussen auction, 2014)
