"Danskjävlar" can be translated into both "bastard" and "devils". We use it a lot in our swearing, and it's a curse word that has many meanings, depending on the situation and whatever word you put in front.
Anyways, while the term is old (I'm from Gothenburg after all, and there's a classical apathy against the Danish here due to historical reasons. Some serious, but mostly very unserious), it got legendary status in the Danish series "Riket" by Von Trier. The same series have been redone by Stephen King as "Kingdom Hospital".
(He watches Barsebäck, a Swedish nuclear plant across the bay, and sing the intro to "Änglamarken")
"Thank you, Swedish watch towers
With plutonium we force the Dane into submission
Here Denmark! Shat out from lime and water
And there! Sweden, chiseled out from granite
Danish bastards!
Danish bastards!"
With that out the way, lovely painting

Any chance for a close-up?
