Design in 1776 was during an era of pen and ink,
steel plate engraving and moveable type.
Illustrators of this time painstakingly used a feather quill and ink well
to capture their imagery on handmade paper of the time.
No erasing or "undo" with pen and ink.
But the 1700's also saw the rise of printing in the Americas, such new "magazines" such as Franklins "Poor Richard's Almanac".
Thus, I feel, starting off a new world of creative arts, the graphic designer.
