DISRAELI DOCUMENTS
This is a spectacularly bad scan of an advert for Le Rectiligne 'S-B'. It is pretty uninformative - but it is extremely similar to a my, more information-rich leaflet. This allows me to estimate the leaflet's date with reasonable accuracy.
Note that the Caminade brand is nowhere to be seen.
