Ohrdruf notgeld of this type was issued under the acute small-change shortage that gripped Germany in the final year of the First World War, when hoarding of metal coinage — even base metal — had stripped municipal circulation bare. City councils across Germany were legally permitted to fill the gap with locally printed emergency fractional notes, and Stadtrat Ohrdruf was among hundreds that did so in 1918.

The single signature, Rötter, almost certainly represents a municipal treasurer or burgomaster countersigning rather than a printer's imprint. Ohrdruf itself housed a significant military training camp throughout the war, which would have intensified local demand for low-denomination exchange media well beyond what a small Thuringian town would otherwise require.
