Hans Hansan was a Danish silversmith. His patterns, mostly from the 1920s, are primarily Art Deco in design. He was from Koldridge, Denmark, so I can only assume that was the basis of this pattern's name.
Normally I stick to American Sterling, but I thought I would venture out in case someone found some of is pieces in their Grandmother's buffet.
