The paper soldiers that you show were printed in sheets on ordinary paper, you then pasted them onto suitable cardboard, cut them out and gave them wooden stands to give you a figure.
They were made famous by the collections of Boersch and several other artists, whose collections are in the Model Soldier museum at Strasbourg, the Army Museum in Paris,
They were the forerunner of the flat figures and due to their cheap method of production very popular.
You can still obtain various versions of the figures they usually come up for sale on EBay.
Paul Martin a French author has written several books and articles on the subject which you should be able to find still, and is the authority on this subject.
Frederick Berjaud still produces his own version of cut out figures to a very high standard and he can be found on the web.
The other site of interest is Miniatures Militaress Alfons Canovas who has many illustrations of the Carl Schmidt Napoleonic figures which are suitable for mounting.
The Paper soldier Museum Strasbourg did produce several booklets of cut outs and may still be available try Amazon France.
Pinterest also show many types of paper soldiers although, they are in the main not Napoleonic but they do have a good set on the battle of the Little Big Horn and Agincourt.
Hope this helps
