Beautiful Green Majolica Swan Planter / Marked "Made in Portugal"/ Unknown Age

I was at out local GW yesterday morning and there wasn't much of anything. I went back later with my friend and they had put out someone's "swan" collection. There were about eight pieces and I wanted them all ! They all had hefty price tags too. One was a Murano swan bowl which I looked up online to make sure. A couple of very thin necked ruby art glass ones. Some vintage art pottery ones and this green majolica one. It's marked made in Portugal and is 10" long x 8 1/2" tall. I love the way she's preening her wing and the detail. You can even see her feet that are bent back as she glides through the water. It's obviously a planter but it was never used because it's clean as a whistle and in perfect condition. I believe being from Portugal it's probably majolica but I really have no clue as to the age. A beautiful piece of pottery ! -Mike-
