How much is My Painting worth?

So I picked up this painting yesterday from A garage sale. It looks interesting though. It seems like the painting is done on an actual canvas or on wood. There is actual texture on the painting and it's not smooth (like on a poster). The painting is "Girl playing a Lute" Maitre Des Demi. Another thing that caught my eye was the frame. Its a old run down frame but on the back, it says Art Acadamy of Chicago. That means it could be an original piece no? Anybody have any idea how much this thing could be worth or to tell if it's an Original?

<That means it could be an original piece no?> No, it's not the original, it's certainly a reproduction. Prints of this painting can be had for $50. You may have an older oleograph of it, though, but I don't know how much value it might have. I've read it might depend in part on whether it's copied on paper or canvas. Sorry to disappoint you, but you're not going to pay for your kid's college education with it.

It's lovely! You just bought it, right? So you know better than anyone how much it cost.
