Vintage Portraits of Historical People - Dolley Madison Estate 1800's

Vintage historical portrait of famous people. Four Round Wall Hangings. Dolley Madison estate sale? Very old and there is wear due to age along with some water damage. I picked this up at an auction. There is old writing on the back of one of them. I can't read it all due to ink fading but says the sale of Estate of Dolley P. Madison, wife of President James Madison. And it is signed. I can not verify or guarantee that they were hers but certainly very unique. Great pieces if someone wanted to investigate more. Diameter 3-1/2". Estate ad is from internet for reference, not included.
