Postcard showing a photo of the Grandin Advertising building, c. 1910. C. W. Post (1856-1914) first visited Battle Creek as a patient at the Battle Creek Sanitarium. He started the Postum Cereal Company in 1895, introducing a cereal drink, Postum, at that time and Grape Nuts cereal in 1897. In 1908 he started production of Elijah's Manna, a flaked corn cereal that later became known as Post Toasties. Grandin Advertising was a company he founded to handle the advertising business of the Post Company, in some years over $1,000,000 per year. This building also housed the Postum Company Administrative Offices. Post was accused of founding Grandin in 1903 to circumvent commissions paid to other advertising agencies. Caption on front: Where Postum, Grape Nuts and Elijah's manna Advertising is Prepared. Perhaps the most unique and handsomely furnished General Office Building in the World. All details pertaining to the annual appropriation of One Million Dollars for Advertising Postum Food Coffee and Grape-Nuts are handled in this building.
