When it comes to autumn, the way to sell groceries is to remind people of that nostalgic peaceful harvest time that never was, where baskets and wooden boxes of colorful fruits and vegetables sit outside under golden leaves and a perfect blue sky. Well, wait a minute, that describes a situation that's all over Mid-Atlantic rural areas right now. Come back to the harvest home you dreamed of with the Trader Joe's fall flyer, the advertising booklet that features goodies for the season. This is the "indicator" which is placed in the store next to the flyer-advertised items. The original is black ink on white paper, about 5 inches by 5 inches. It's printed on bright orange paper.
