The sender is from North Carolina, but she purchased her card from Nebraska, where her son lives. This is a watercolour created by William Henry Jackson showing Buffalo Bill Cody. According the the card: For 18 months the Pony Express carried the mail from St. Joseph, Missouri, through Nebraska, Colorado, Wyoming, Utah, Nevada, and ending in Sacramento, California. Buffalo Bill Cody made the longest non-stop ride of 322 miles over one of the most dangerous portions of the entire trail in 21 hours and 40 minutes using 21 horses.
