This magnet pictures a November, 1956 advertisement for Western Union telegrams featuring Cecil B. DeMille (1881-1959) who was working on the Ten Commandments released the same month.
Over nearly four hours, the film told the epic Biblical story of Moses leading the Exodus to deliver enslaved Hebrews to Mount Sinai and receiving God's Ten Commandments. Among the cast of thousands were stars Charlton Heston, Yul Brynner, Anne Baxter, Edward G. Robinson and Yvonne De Carlo. Shot on location in Egypt and the Sinai Peninsula, the film was the last of DeMille's seventy films as well as the most costly and most successful. It would be nominated for seven Academy Awards and gross over $122 million.
Western Union was formed in 1856 by merging two New York companies. The company grew rapidly and along the way was responsible for many "firsts," including the stock ticker in 1866, money transfers, charge cards, teletypewriters, singing telegrams, Telex networks and candygrams. The Wikipedia writeup about Western Union is detailed and interesting.
There are still companies providing telegram services but after 155 years as the name most synonymous with telegrams, Western Union ended that part of its business in 2006. At that point its annual telgram volume had dropped to around 20,000 – from its 1929 high of 200 million.
Today's Western Union Company is based in Meridian, Colorado. It continues to offer money transfers, money orders, business payments and commercial services.
