Widely held as the first national park in the world, Yellowstone National Park was established in Wyoming by the U.S. Congress and signed into law by President Ulysses S. Grant in 1872. The park thrived, so much so that the Greyhound bus company, founded in Hibbing, Minnesota in 1914, eventually dedicated one of its routes to deliver wide-eyed passengers to Yellowstone’s spectacular grandness. The 1960s “Go Greyhound” poster presented here was designed by H. Goodwin, featuring a few of the park’s “greeters,” an imposing grizzly bear and cubs.
