Unknown Austro-Hungarian Banknote [resuelto]

Hello All,

This is an Austro-Hungarian banknote that I have had for a long time and couldn't have found anything related to what sets this apart from all the rest of them. It is a regular paper with 125 mm in length and 82 mm in width. 

The reason why this makes this different is the overprint near the bottom on the reverse which states:

“Kære Ven” “27, Vestergade 27”

I have tried looking for any indication for if there is reasoning behind it but there seems to be no research behind it. 

Hope this helps!

Huh, so it should just be chalked up to a private touristy motto printed? It would make sense given the fact that so many were printed and the country would have been dissolved before this was added on.
