If any of the images are famous, you may want to check and see if the copyrights have been renewed on any of them, death does not always invalidate copyright and as I remember it, the copyright law was redone a couple of years ago, to go back as far as 125 years, as far as reproduction, that is going to be something you have to make the choice on, if you choose to do it, I would say you would need to note they are not your images and are reproductions of others work.
