This portrait (https://www.wikitree.com/photo/jpg/Rittenhouse-763) used to hang on the wall of Catherine (Rittenhouse) Turner. It's described as quite a large oval picture, and "When looking closely there is some crazing throughout the portrait, but it is hard to tell the medium." It's presumably of an American since it belonged to one. Unfortunately there is no writing on the front or back to identify it. We're not sure whether it's a family member and therefore of considerable interest to the family, or just a celebrity. Does anyone recognize either the person or the uniform?
