This is an exciting find!  Made in England by Porter and Moore in the 1930's, this special bottle is frosted molded glass in the shape of the Bonzo the dog.  His name is actually molded into the glass on the back of his neck but unfortunately, this is where the only chip on the entire piece is found.  Please see the photos.  The words "Registed Design" are also molded on the back of the piece at the bottom rim.  The bottom of the piece also shows the maker's mark as well as the small black lid shows "Porter and Moore".  The bottle stands 3.3 inches tall, 2 inches wide and 2 inches long.  If you pull of the dog's head, the original cork is revealed as well as the bottle's small black lid.  There is a small amount of dried perfume in the bottom of the bottle and therefore the scent of perfume still exists.  Just so you know!
