LINCOLN, Neb. (AP) — Nebraska celebrated 150 years of statehood on Wednesday with tributes to its pioneer roots, history-making citizens and natural splendor.

Hundreds gathered at the Capitol to mark the anniversary with the formal unveiling of a new state stamp and actor portrayals of author Willa Cather, Ponca Indian Chief Standing Bear and William “Buffalo Bill” Cody.

The state stamp formally unveiled at the Capitol shows Sandhill cranes flying over the Platte River in central Nebraska. It’s from a photo by Lincoln photographer Michael Forsberg.
