Denmark adopted adhesive stamps in April, 1851, when the 4 rigsbankskilling stamp was issued. A 2 rbs value, for Copenhagen local letters, was issued later the same month.
The stamps were engraved on steel by M. W. Ferslew and typographed by H. H. Thiele of Copenhagen. It is thought that the first printing of these stamps may have been produced by Ferslew himself, since the colour of the background wavy lines varies considerably.
The majority of Danish stamps (until 1933) and Icelandic stamps (until 1925) were printed by Thiele.
