Gladys George Painting

I found this painting 2 summers ago at a yard sale for $5.00 near Plattsburgh NY. The name on the bottom of the painting says Gladys George and i wanted to know if the Gladys George that painted this painting is the same Gladys that pops up when i search the name. all Ive been able to find out is information about an actress (http://en.wikipedia.org/wiki/Gladys_George ) on the back of the frame is says 'G. George 399-0478' theres no area code if its a phone number. it measures 24 inches in height (up and down) and 18 inches across. (left to right) I wanted to know if this is a painting by the actress and if so, for insurance, id want to know how much its worth.
