Japanese Avocado Green & Metallic Gold Vase with Relief of Jay Bird & grapes

Once upon a time this had a made in Japan sticker on it but that came off before I could photograph it. Based on the country of origin and colors I think this was probably made in the 1970s but could be as old as the 1950s. It’s in great condition no chips or cracks. I love it not only for the detail but the unusual shape which I’ve been pondering for a while. I’m not sure if there’s a specific use for this or the artist simply liked it! Photos include all sides of the vase as well as the inside and a few close-ups of the relief work. Note: all my breakable items are packaged in bubble wrap and surrounded by peanuts. Your box will be much bigger than the actual item.
