Art Deco Vaseline Glass Vase or Aquarium

Good Day,

I have what I believe to be either a vase or an aquarium. It's a brass or bronze metal base sleeve with grape leaves on each of the four sides and a green vaseline glass rectangular insert that slides nicely into its metal sleeve. Something I read a while back has lead me to believe it's from the 1920's. I've researched this item for a while now with little information found. Size is approx 20 cm x 12 cm x 7 cm I'd like to know anything that anyone may know about it, as well as it's approximate value? Any advice will be much appreciated. I'm new to this site. Thank you all!
