The bowl verses

What makes the Holter glasses so special is that, in addition to pictures of Norwegian industry, they also have bowl verses with content that intervenes directly in the current political situation. 

Many are quite outspoken in terms of expressing dissatisfaction with Norway's position in the dual realm. In a private context as a bowl verse, you could take a little in and not be so careful with the truth.
It was undoubtedly important for the creation of the verses that Struensee on 14 September 1770 introduced freedom of the press in Denmark-Norway. The freedom of the press lasted only until October 20, 1773.

Pessimism

In several of the verses one can trace a pessimistic attitude. In the agricultural verse it is stated that bogs and scrub have taken over where there used to be fertile soils. Trade and shipping go with Krebsen, that is, go backwards.
There were bad times in Norway in the early 1770s, but pessimism is another form of crisis maximization to make it clear that it was Denmark that was to blame for the misery. 

A harsh attitude towards Denmark is repeated in several of the verses, perhaps most clearly in the verse about salmon fishing:

Here Laxen Strebe must face the stride Fos
Maybe it should be a picture of us
What does it have for all its strength and effort
Only that its obesity can a duck readily satisfy

Like the Norwegians, the salmon struggles and struggles in countercurrent, but the result of the struggle is the other, that is, the Danes, who get fat. The same is true of the pot verse. It is Denmark that benefits from the hard work of Norwegians.

Here we make and even Potash
And we strive for everything
But the money is the same wrong
They run Well to the bag of others.
