What book lover hasn’t, especially in this alarmist age, worried about art being trampled by commerce and quality being eroded by the demands of popularity? $100K is still a substantial price tag, but this could make community printing presses a feasible approach. This is just one more example of the traditional media monoliths breaking down into flexible, postmodern units. Marvellous!
