A hand written chord chart—mostly first and second position chords—from my studio teaching days circa 1981! In those days, teaching materials—music sheets, scales, technical exercises, etc.—were written with pen and ink. Computer music notation and graphics didn't exist yet. And the internet was still a twinkle in the eye of its creator.
The small numbers below the chord diagrams are suggested left-hand fingers. The long curved line indicates a barré.
