Tombstone Thunderbird

One of the first reported sightings of a Thunderbird occurred in April 1890, when The Tombstone Epitaph reported that two cowboys in the southern U.S. had killed a large bird-like creature with smooth skin and wings. For years, rumors circulated that an accompanying photograph of the capture existed and was passed around before eventually getting lost sometime during the 1960s. To date, the alleged photo has not surfaced. 

This is an artist's rendition of the famous thunderbird photo said to have appeared in the Tombstone Epitaph, an Arizona newspaper in the 1890s.
