The caption for the group picture is as follows:

Ginger Goodwin is the man on horseback in this historic picture of officers of the Western Federation of Miners taken just before the start of the May Day parade at Trail in 1917. Goodwin, who organized the victorious 1917 strike in which 3,000 workers walked "off the hill," led the parade on horseback.
