This is a mystery. The title page indicates that this was created by someone at MIT, but without a full name it is difficult to decipher whether this is a professor or a student. The drawings are well executed images of mathematical and architectural elements, drawn in fine black ink, with watercolor enhancements to some to introduce color or patterning to the drawing. A lovely portfolio with attractive and artistic rendering.
