Copenhagen arms and some flags
When I use my handicam in the archives the results go in for example
on the way out of the city hall this coat of arms in the enquiry office by main door caught my eye
what are these yellow or blue flags with the Dannebrog quartered?
see Flags of the World but unknown
INSIGNIA REGIA CIVITATIS UBERA HAFNIENSIS
Hafnia is latin for Copenhagen well Kjøbenavn or Köbenhafn to mention a couple of the early spellings
a square Dannebrog suggest an early date if authentic
