Greetings,
We have a series of prints by J. Franklin Brown of the Western Rivers Steamboats collection.
We have: "Trimble, City of Louisville, Washington, Joe Fowler, Delta Queen, Belle of Louisville, Betsy Ann, City of Madison".
These are detailed penciled drawings from original photographs.

We would like to know if they have any value and, if so, what their value might be.

Thank you for any help you may offer.

Art Mengel
