Peale Museum Silhouettes?

The following comes from one of our readers, Michael. I'm gonna let the readers respond to this one.

Saw your website and was wondering if you might can tell me about these silhouettes. Are they real??? Are they collectible???? etc... The peale's museum is visible under her bust line. The eagle has almost been cut off but you can see it. I darkened the pictures of the name to enhance it. There is also a ghost?? Image around the outline of the woman like it is impressed on the paper but not cut out. The man also has a stamp but you can just barely make out a couple of the last letters in museum. The silhouettes are hollow cut on wove rag paper. I took the back off and they both have the amies paper mill watermark from Philadelphia.

Size of the paper is approx. 4 3/4 by 3 1/2. The actual silhouette size of the woman is approx. 2 5/8 by 1 1/2. On back it says George c. Wilson and under the cardboard back is says property of Kate Wilson.
