Henry J. Heinz introduced the marketing slogan "57 pickle Varieties" in 1896. He later claimed he was inspired by an advertisement he saw while riding an elevated train in New York City (a shoe store boasting "21 styles"). The reason for "57" is unclear. Heinz said he chose "5" because it was his lucky number and the number "7" was his wife's lucky number. However, Heinz also said the number "7" was selected specifically because of the "psychological influence of that figure and of its enduring significance to people of all ages". Whatever the reasons, Heinz wanted the company to advertise the greatest number of choices of pickles. In fact by 1892, four years before the slogan was created, the Heinz company was already selling more than 60 products.
