This is a gloriously decorative piece. 
It is an antique ridge tile otherwise known as an antefix. 
It would have sat on a roof at the top of the eaves to finish off the ridge tiles in a beautifully decorative fashion. 
This would make a fantastic piece in the home, sat on a shelf or on the coffee table on a pile of books. 
If you like the quirky and unusual. . . something that is a complete conversation piece, this is it!
