I did not know that yesterday!

I typed "www.heinz.com" into our browser's location bar, and was quickly rewarded with the Heinz web site, and clicked on the Consumer FAQs section, always my first stop when looking for an answer to this type of question. I scanned the entries and soon found a similar question:
What is the significance of "57"?.

Here's the company line:

Our corporate history tells us that in 1896, Henry John Heinz noticed an advertisement for "21 styles of shoes." He decided that his own products were not styles, but varieties. Although there were many more than 57 foods in production at the time, because the numbers "5" and "7" held a special significance for him and his wife, he adopted the slogan "57 Varieties." So, the number 57 isn't related to the number of products offered by Heinz. It is interesting to note, however, that the company currently sells 5,700 varieties in 200 countries and territories.
