​Wisconsin's Flag History

Starting at the top of a shield on a dark blue field is the state motto "Forward". Below it is a badger the state animal. A sailor and miner show that the people work on water and land. The shield in the center shows Wisconsin's support for the United States. In four sections surrounding the shield are representations of the states main industries: Agriculture, mining, manufacturing and navigation. The cornucopia and pile of lead represent farm products and minerals. The flag was adopted in 1913. The flag law was amended in 1979 to include the name of the state and the date of statehood.
State flag. (1) The Wisconsin state flag consists of the following features:

(a) Relative dimensions of 2 to 3, hoist to fly.
(b) A background of royal blue cloth.
(c) The state coat of arms, as described under s. 1.07, in material of appropriate colors, applied on each side in the center of the field, of such size that, if placed in a circle whose diameter is equal to 50% of the hoist, those portions farthest from the center of the field would meet, but not cross, the boundary of the circle.
(d) The word "WISCONSIN" in white, capital, condensed Gothic letters, one-eighth of the hoist in height, centered above the coat of arms, midway between the uppermost part of the coat of arms and the top edge of the flag.
(e) The year "1848" in white, condensed Gothic numbers, one-eighth of the hoist in height, centered below the coat of arms, midway between the lowermost part of the coat of arms and the bottom edge of the flag.
(f) Optional trim on the edges consisting of yellow knotted fringe.
