Enamelled plate "grande ceinture"

Large and rare nameplate of the large belt (https: //fr.wikipedia.org/wiki/ligne_de_la_grande_ceinture_de_paris). Edited by the enamel factory edmond jean (https: //patrimoine.seinesaintdenis.fr/emaillerie-edmond-jean), This plate is from the '20s/30s. We notice, on the right & left, the impacts of 50mm caliber bullets, the caliber of the german army during the second world war! The photos show his condition, well preserved for his great age! Model not found, except here...; -) Two plates of 172.5 X 40 cm.
