Lyrical Antique Graphite Drawing of Two Geometric Volumes

I find this graphite drawing quite beautiful, especially for the subtle wavering of the lines, appearing to have been drawn freehand rather than with a ruler. Which makes it feel quite expressive, and lyrical, and alive. Lovely.

11 1/4" x 8 3/4" and in very good condition, c. 1900 or so, I believe. A little loss/irregularity to the upper right edge of paper.
