This picture is a historical depiction of the Montana Territory's coat of arms, as illustrated by American engraver Henry Mitchell in State Arms of the Union, published in 1876 by Louis Prang. The shield depicts a landscape of mountains, plains and forests by the Great Falls of the Missouri River. A plow, a pick and a shovel are depicted in the foreground, representing the territory's industries. Below the shield is the Spanish motto Oro y plata, meaning 'Gold and silver'. The same design is featured in the current seal of Montana.Illustration credit: Henry Mitchell; restored by Andrew Shiva
