"Bounded by the Hoops of Economy, Driven by the Hands of Industry" is the slogan on one side of a painted linen banner created by the coopers' trade group of the Maine Charitable Mechanic Association in Portland.

Group members created this and 16 other trade banners that they carried in a parade Oct. 8, 1841 through the streets of Portland as part of a Triennial Festival that celebrated both civic pride and the achievements of skilled artisans.

The other side of the banner reads, "Nothing but Division can ever "Square the Circle" of our Casks."
