Carol Myers of the Saint Nicholas Center wrote and sent a link to the Center's page of coats of arms from around the world with St. Nicholas or one or more of his attributes on them. The page, with links to pages of arms from individual countries, is http://www.stnicholascenter.org/Brix?pageID=429
She writes, "St Nicholas Center, a non-profit with US tax-exempt status, exists solely to spread the word about St Nicholas and to help people understand who Santa Claus/Father Christmas really is. We provide information about the saint, customs from around the world, and a large variety of resources for churches, schools, and families to use to celebrate his feast day. There is also a section for children with on-line activities." The entire site is very interesting, with a lot of information about St. Nicholas, and well worth the visit.
