This is a 19th Century Brass Royal Coat of Arms - HONI SOIT QUI MAL Y PENSE!

This is from an Estate in Connecticut - no other information is available on it, unfortunately.

A particularly decorative and appealing Royal Coat of Arms* made from cast brass. The Victorian coat of arms is raised on an imposing stepped plinth and was designed as a chimney-piece ornament. An attractive and practical item which would also work well as a doorstop, in excellent condition.

* The shield is quartered, depicting in the first and fourth quarters the three passant guardant lions of England; in the second, the rampant lion and double tressure flory-counterflory of Scotland; and in the third, a harp for Ireland. The crest is a statant guardant lion wearing the imperial crown , himself on another representation of that crown. The dexter supporter is a likewise crowned English lion; the sinister, a Scottish unicorn . According to legend a free unicorn was considered a very dangerous beast; therefore the heraldic unicorn is chained, as were both supporting unicorns in the Royal coat of arms of Scotland . In the greenery below, a thistle , Tudor Rose and shamrock are present, representing Scotland, England and Ireland respectively. The coat features both the motto of English monarchs , Dieu et mon droit (God and my right), and the motto of the Order of the Garter , Honi soit qui mal y pense (shame upon him who thinks evil of it) on a representation of the Garter behind the shield.
