Ruth-c1940

Who knows what she was thinking when she doodled this little drawing
on the back of a photo.

This talented lady was an accomplished draftsman.
Working full time for Pacific Telephone she drew the wire routes
under the the streets of Los Angeles, and later, wiring diagrams
of ships for the U S Navy. After her eyes refused to let her
work full time, she freelanced as a catalog illustrator.
