Historical Map: Old Paris Metro Map at Marcadet Poissonniers Station (pre-1967?)
Great photo of the remnants of an old Metro map. The original poster of this photo on Flickr notes that it’s normally hidden behind advertisements these days. The best I can do with dating is pre-1967, as Line 7 has yet to be split into 7 and 7bis north of Louis Blanc station, instead being branches of the same line. Source: andrew gallix/Flickr
