Yup, it sure is, but they did several styles of Angel 3 to my knowledge, and the one in the box was the same style as the bird and the tree....wish I had bought it now, but the bidding went too high. They did a star as well......but I don't think that was in the boxed set.
I have to be honest and say I prefer your Angel, much prettier and with more detail.
I'll see if I can find some reference to the boxed set, as that does then help.
Added 09.36am: Anik, just had a better look at your Angel, and on reflection, looking at the little droplets on the skirt, I think yours WAS the one in the set. I don't remember the wings being so pretty. I guess I was focusing more on the bird as I was feeling so guilty about mis selling it.
