How much is my J.Perrine painting of a garden party with people in hats and women holding umbrellas worth?

I have a J.Perrine painting that is 30"x24" and the frame measures 38"x32".
The scene is a garden party by a lake with people dressed up in hats and
women with umbrellas. Wondering if anyone has an idea of what this
painting could be worth. Any information would be helpful, thanks.
