La serrurerie
La serrurerie is a French guide to ironwork and locksmithing by Henry Havard, published in Paris by Delagrave in 1921 for craftsmen and students of decorative metal. The pictures show wrought-iron scrollwork, a decorative gate with a crowned arch, an ornate key, and a carved chest, with dense curling ornament a designer could draw on for patterns, borders and wrought-iron motifs.
