Striking Vintage Geometric Drawing in Blue and Red Ink blocks in wooden box but plenty they could spell

but plenty they could spell out without them

and this interesting sort of abstract form at right

I'm completely smitten with early schoolgirl theorem watercolors

cylinder and sphere-that suspended by string from a wooden armature

with leafy curtain raking across the frame in the other direction

Striking Vintage Geometric Drawing in Blue and Red Ink blocks in wooden box but plenty they could spellA drawing like this really makes me want to sit down with a protractor and compass and ruler and spend the day trying to make something as satisfying as it is! Oh, the joys of geometry, and symmetry, and here all those straight lines in red and blue. Initialed at bottom left and dated 1990, I would think this was done as an art school exercise, but encountering it now it feels close kin with 19th c. mensuration notebook diagrams I love so much. Nice.
