AI-assisted summary
Description from the seller
Original technical drawing – 'Engine cover (section and plan)' – École Professionnelle de Mécanique, ca. 1910–1920
Rare original hand-drawn technical teaching plate, originating from the École Professionnelle de Mécanique (O. Hautcoeur, E. Thys, U. Valentin & Cie), led by Ulysse Valentin, professor of auto mechanics in Huy (Belgium).
This particularly fine drawing depicts, in cross-section and top view, an engine housing (or crankcase), with details of the bearing housing, fastening bolts, seals, and screw connections. The figures show both the cross-section A–B and separate technical details (such as bolts and seals).
The drawing combines technical precision and artistic finishing, with characteristic hatching and pastel colors (pink, green, yellow, and purple), executed in Oost-Indische inkt and watercolor.

Details
Original, hand-drawn technical educational plate
Signed by Ulysse Valentin
Detailed technical cross-section of engine block and suspension.
Decorative and rare, ideal for framing.
This drawing was used around 1910–1920 in technical education at the École Professionnelle de Mécanique to teach students about the construction and operation of motor housings.
Such plates were entirely handcrafted before the advent of printing and CAD drawing, representing a time when engineering, education, and aesthetics came together.
A unique historical document from the early years of automobile technology — both educational and artistically valuable.
Short biography of Ulysse Valentin
Ulysse Valentin (active from the early 20th century) was a professor of automotive engineering in Hoei and Marchin (Liège province, Belgium). He trained young technicians and driver-mechanics during a time when the automobile was still in full development. Valentin was known for his didactic approach, producing large and precise diagrams that helped students understand the workings of engines and vehicles.
His education reflects the transition from horse-drawn carriages to cars. The signatures and stamps on his students' drawings and diplomas make these documents valuable testimonies of the early history of motorsport in Wallonia.
