Art- day 15. Look what I found.

Found these in the house. They were in a black plastic bag. My Aunt went to art college in 1947 and they were all drawn by her. Sadly she is no longer with us. There were loads more in different styles, but these are the most impressive.  
I'm foraying into areas of the house I have not looked in for years. What can I do with the sketches? I cannot bear to part with the images; they  have too much sentimental value.
