-The ‘flags’ (really coat of arms) for the pre-2020
-Norwegian counties were downloaded from Wikipedia

-on 2018-08-27. They were then converted to PNG

+The ‘flags’ (really coat of arms) for the Norwegian
+counties have all, except for Oslo county, been taken
+from the official graphic profiles of the counties.
+They were then converted to PNG files with a common
+height (200 pixels).
 
-For the new counties (official from January 2020),
-the coat of arms of Agder, Innlandet, Vestfold og Telemark,
-Vestland and Viken have been taken from the official
-graphic profiles of these counties. For Troms og Finnmark,
-a (temporary) coat of arms have been created by merging the
-(Wikipedia) images of the coat of arms for the two (pre-2020)
-counties Troms and Finnmark.
-
-Note that the images at Wikipedia have been improved
-over time, so the KGeography images should probably
-also be updated in the future. And the coat of arms
-should be taken from official sources (instead of
-from Wikipedia) if possible.
+The coat of arms for Oslo county have been taken from
+Wikimedia Commons (downloaded on 2018-08-27):
