Two different labels of Swedish Mink, engraved by Czeslaw Slania. 

The scan is submitted by Mr. Jerzy Krysiak (Sweden). He tells that Mr. Slania left no information about these labels, only that he received the order for the engraving sometime during the 1970s. Only very few are known to exist, and belong to Swedish collectors.
