Leona Lindvig (late 20th century) Leona Lindvig was active/lived in United States. There isn't any more information about the artist biography. This is normal for local artists. However there is a good record of past auction sales for original oil paintings from her.
Regarding the value of your item, I have just perform a market research of similar sold items as yours. I performed the research based upon the most recent finished auctions and private sells, so the value given is the real market value of your item. This is the only way to know the exact value of your unit.
The value will be in the range of 500-700$.
