Watch List notes:

Austria: 5 Kronen 1918 similar to P. 22 but unknown type, consisting of 2 halfs put together in center, back printed, front side only proof print without writing. There were no records found about this note to be original or fantasy issue. Until now no note like this with printed back was found on the market. The print seems original and the paper it is printed on is NOT UV-active so it seems to be real banknote paper. Probably rare and unique item.
