Eggleston's mature work is characterized by its ordinary subject-matter. As Eudora Welty noted in her introduction to The Democratic Forest, an Eggleston photograph might include "old tyres, Dr Pepper machines, discarded air-conditioners, vending machines, empty and dirty Coca-Cola bottles, torn posters, power poles and power wires, street barricades, one-way signs, detour signs, No Parking signs, parking meters and palm trees crowding the same curb."
Eudora Welty suggests that Eggleston sees the complexity and beauty of the mundane world: "The extraordinary, compelling, honest, beautiful and unsparing photographs all have to do with the quality of our lives in the ongoing world: they succeed in showing us the grain of the present, like the cross-section of a tree.... They focus on the mundane world. But no subject is fuller of implications than the mundane world!" -- from Wikipedia quoting Eudora Welty in [Eggleston's] Artistic Development].
