There is a Swedish online market place that dates these to around 1910. Vayolene's source might be correct.
However, your example with a date stamp for 1914 could be another indication.https://en.wikipedia.org/wiki/Gustaf_V
The King and defence were issues in Sweden in 1914:At first, Gustaf V seemed to be willing to accept parliamentary rule. After the Liberals won a massive landslide in 1911, Gustaf appointed Liberal leader Karl Staaff as Prime Minister. However, during the runup to World War I, the elites objected to Staaff's defence policy. In February 1914, a large crowd of farmers gathered at the royal palace and demanded that the country's defences be strengthened. In his reply, the so-called Courtyard Speech—which was actually written by explorer Sven Hedin, an ardent conservative—Gustaf promised to strengthen the country's defences.
