The fledgling project was marred by economic problems, and the burden of both writing, editing and printing lay chiefly on Knudsen.

[7] Jæger and Knudsen later tried to circumvent the law and sell the banned book in Sweden, brandishing a fake name Julefortællinger af H.J.

[6] Knudsen also received a jail sentence, of eleven days, for publishing a piece about contraception in Social-Demokraten in 1887.

Like the trade unions, the early Labour Party contained both socialist and non-socialist elements.

[2] Knudsen was a deputy member of the Norwegian Nobel Committee from 1913,[1] and served his third term as party leader from 1911 to 1918.

His leadership came to an end when the radical wing, spearheaded by Kyrre Grepp and Martin Tranmæl, took over at the 1918 national party convention.

When the less radical wing broke out to form the Social Democratic Labour Party in 1921, Knudsen did not follow; he continued in the central committee until 1924.

This contract was renewed several times and was maintained by his Trustee, Gunnar Meyer, from 1929 until 1937. Notable issues (by letterpress) include the 1895-1910 Posthorn, the 1909-1937 "redrawn" Posthorn, the King Haakon VII kroner values, 1907-1936, and the Rampant Lion series I and II, 1922-1937.
