Paris, France (Publisher Trademark)
J. L. C. may have been the initials used by the Parisian postcard publishers H. Jullien and Charles L'Hôpital located at 39, Boulevard de Strasbourg, Paris. The trademark used by J. L. C. adds the words Le Gui (the mistletoe). If this is correct, the initials stood for Jullien, L'Hôpital & Compagnie. See also C. L. C.
