The Printers group of the Maine Charitable Mechanic Association represented their trade with illustrations of four men at a printing press and a Tuttle's patent press and the words "Fulcrum for Archimedes' Lever."

Archimedes is quoted as saying if he had a place to stand, he would move the earth, a quote that often accompanies an image of him pushing on the end of a lever that has the globe on the other end.

The other side of the painted linen banner has the words "The Tyrants's Foe: the People's Friend" surrounding two illustrations of printing presses."

The group participated in a parade on Oct. 8, 1841 in Portland with 16 other artisan groups of the Charitable Mechanic Association, a group that supported and promoted skilled artisans.

Arthur Shirley and Samuel Colesworthy, Charitable Mechanic members, painted the banner.
