As Nevada prepared for statehood in 1864, its Constitutional Convention began to formalize the features of the state's official seal.

Transportation and communication are symbolized by a train steaming across the background, with telegraph poles spanning the distance.

Nevada's natural environment is symbolized by a brilliant sun rising over snow-capped peaks.

The inner circle of the seal carries the motto "All for Our Country", and Nevada's entry into the Union as the 36th state is shown with 36 stars completing the inner ring.

Mark Twain was said to have convinced the designer to make the two trails of smoke blow in opposite directions as a prank, which was later rectified when the mistake was realized.
