The name Le Coq, LeCoq, Lecocq is common in Amiens so this must represent a local firm, but it seems unlikely that it will have produced thousands of photographic postcards of this type by itself, rather acting as a reseller.
A few publishers have used a cockerel in their logo.
Others represented here are
Gallia, Paris,
an unidentified publisher and
Ch Ramel & Cie, Paris.
Others are
Lecocq, tabac, Clermont sur Oise (views) and H. Lecoq et Mathorel, Alençon (views, printer).
