I have a collection of clippings of newspaper articles from the 1860's and 1870's. These are reviews of the book and of the various non musical theatre productions (atonement, the barricade,yellow passport and valjean). I cannot post them here for copyright reasons but I am happy to share them as a zip file to anyone who wants them. They give a good insight into how popular the story was back then. Apologies if I posted this in the wrong place.
