Two Technical Architectural/Furniture Drawing Plates

A pair of hand-rendered technical drawings or 'plans techniques' depicting the design and internal structure of cabinetry or a wooden casing system. These two large-format horizontal sheets, rendered on off-white or cream-toned paper likely from the mid-to-late 20th century, exhibit professional-grade orthographic and isometric projections. The top plate illustrates front and side elevations alongside an isometric 'ghosted' view of the unit's frame, accompanied by what appears to be a bill of materials or a 'Liste des matieres'. The bottom plate focuses on detailed joinery, exploded views of side panels, and assembly instructions, including shaded sectional details indicating depth and material thickness. Both sheets feature hand-lettered French annotations and precise linework. The condition is fair to good, showing minor edge wear and slight tonal yellowing consistent with age and storage. The craftsmanship suggests either vocational student work ('Chef-d'oeuvre') or professional carpentry workshop plans. There are no prominent stamps visibly identifying a specific firm, yet the grid-less layout and manual drafting style highlight individual technical skill before the digital CAD era.
