A grocery shelf displays various heads of lettuce

A grocery shelf displays various heads of lettuce. Some are loose-leaf, bright green in color, while others are tightly packed iceberg lettuce, partially wrapped in clear plastic. A sign reads "Eisbergsalat" (iceberg lettuce). A paper advertisement is visible in the upper left corner. A sign for "Kontrolle s Vertrauen" (Control and Trust) and details about organic certification is in the upper right. The lettuce is arranged in a black plastic crate.
