vintage Murano style Sooner art glass swan, slag glass bowl or planter lemon pie yellow & white

I love the unusual light lemon yellow color of this vintage glass swan! I don't know if this is a Sooner glass piece or Murano glass, I've seen so many of these called either one.

It's a lovely hand shaped piece in any case, and vintage. Measures about 11 1/2" long overall, 7" tall. It's in excellent condition without chips or cracks.
