For the past decade, Bill Keaggy, 33, the features photo editor at The St. Louis Post-Dispatch, has been collecting grocery lists and since 1999 has been posting them online at www. Grocery lists, org. The collection, which now numbers more than 500 lists, is strangely addictive. The lists elicit two-fold curiosity—about the kind of meal the person was planning and the kind of person who would make such a meal. What was the shopper with vodka, lighters, milk and ice cream on his list planning to do with them? In what order would they be consumed? Was it a he or a she? Who had written "Tootie food, kitten chow, bird food stick, toaster scrambles, coffee drinks"? Some shoppers organize their lists by aisle; others start with dairy, go to cleaning supplies and then back to dairy before veering off to Home Depot. A few meticulous ones note the price of every item. One shopper had written in large letters on an envelope, simply, "Milk".
The thin lines of ink and pencil jutting and looping across crinkled and torn pieces of paper have a purely graphic beauty. One of life's most banal duties, viewed through the curatorial lens, can somehow seem pregnant with possibility. It can even appear poetic, as in the list that reads "meat, cigs, buns, treats".
One thing Keaggy discovered is that Dan Quayle is not alone—few people can spell bananas and bagels, let alone potato. One list calls for "suchi" and "strimp". "Some people pass judgment on the things they buy," Keaggy says. At the end of one list, the shopper wrote "Bud Light" and then "good beer". Another scribbled "good loaf of white bread". Some pass judgment on themselves, like the shopper who wrote "read, stay home or go somewhere, I act like my mom, go to Kentucky, underwear, lemon". People send messages to one another, too. Buried in one list is this statement: "If you buy more rice, I'll punch you." And plenty of shoppers, like the one with both ice cream and diet pills on the list, reveal their vices.
