Hello,My name isCustomerand I would love to help. All three pictures were the same photo of the signature.Please use the Add Files feature on your screen to add pictures of the piece as well. Let me know if there is a label or writing on the back of the framing.
That one is a blur, I don't think you meant to add that picture.
This is a pencil drawing by an artist named Marilyn Heigl done in 1971.
This was done by a student or regional artist near where you found this piece and is not a professional or listed artist piece.
This pencil drawing has a current value of $20.00 retail.

I only contracted to do the one portrait for this question, but I will do this one for you as well.
This is a pencil portrait that was created in the late 1960's or early 70's by a Mary Rose Palau.
This one is a better quality, again likely a student artist piece from your region of the country.
This framed pencil drawing has a current value of $40 to $60.00 retail.
