Egyptian "Roi", C. 1920s-30s Detailed French Ink Drawing 1860s school math book but I really don't know

but I really don't know

or just to throw over the shoulders on a cool spring or fall evening sitting outside

which I believe is a bit of underpainting showing through

3 5/8" x 2 7/16" and in very good antique condition

And the reverse shows a truly apectacular patina

Egyptian "Roi", C. 1920s-30s Detailed French Ink Drawing 1860s school math book but I really don't knowI love the detail on this French drawing of an Egyptian king Roi and the scale of him on the page, like a jewel in the vast. Ink on nice weight cream paper, with graphite visible under the ink as all that detail needed some careful sketching first! Paper: 12 3 4" x 9 7 8". Very good condition.
