Painting

(I've posted for the last three days, click back to see what's what!)

I'm trying to figure out who painted this, where it's from, how old it is, and approximately how much it's worth. I bought it at Goodwill when I got the dress. I saw it and loved it, figured why not and brought it home too. Someone I met there seems to think it could be worth a lot.

If you have any info, please help me out! Thanks! :o)
