Telephone Concept Sketching

from Gizmodo

1st phone sketches by Alexander Graham Bell.

“As far as I can remember, these are the first drawings made of my telephone—or “instrument for the transmission of vocal utterance by telegraph.” -A. Graham Bell”

so cool. I’m at a loss for words when I think about what this sketch represented in its days, and what modern communication technology looks like.

Needs to improve the line weight and perspective.
