Vintage from the 1920's, a linen table centerpiece doily with lace edging of a Viking Nordic influence. The motif is a Nordic woman in a small boat pulled by a swan. 

The lace is probably machine made.  This motif alternates with the head of a Viking.  Flowers and scrolls accent the motifs.  Very pretty and unusual.

The 20" doily has a 5-1/2"  (from the edge to the widest part of the scallop) lace edging. 

Condition:  one tiny pin hole in the linen center.  Some breaks of the bridges or brides that connect the motifs.  Possibly these area could be mended.  Not many but are some.
