Vintage opalescent blue glass, swan trinket/candy dish

This is vintage and previously owned. It is in good condition. No chips or cracks. It appears to be mid 20th century possibly 1970s and possibly carnival glass. It measures 4 inches tall and approximately 5 inches wide and approximately 3 inches in depth. I’m no expert on glass so I’m not gonna guarantee that it’s carnival glass but there’s a good possibility from my investigation. There’s no makers marks. flawless for everyday use. supreme materials and excellent craftsmanship ensure long-lasting durability.
