Large Antique Technical Drawing - Boulogne Harbour - 1869 Rare Poster-Sized Engineering Drawing

A large antique technical drawing of the Boulogne Harbour, France, specifically the "New Floating Basin , 1868 Plan of Culvert Level" Published as a supplement to The Engineer, dated November 12, 1869 (top right of drawing).

Size: approximately 30.5 inches x 22.5 inches (77.47 cm x 57.15 cm)

This rare drawing from The Engineer, one of the world's oldest professional journals, would make a unique present for anyone engaged or interested in engineering or for those interested in Boulogne's history.

The full print is shown in the first photo. Other photos show details from the print.

Printed on thin paper. Small tears along edges have been repaired with archival mending tissue. There may be some chips along the margins, not affecting the image. Otherwise in very good condition. It is quite rare for a technical drawing of this size from the 1800s to have survived, and in such condition, too. Blank en verso. The colour of the paper is hard to capture due to the thinness of the paper, and the photos are an approximation of the actual color.
