Pop-Music Fashion Becomes a Sales Hit
In a converted warehouse at the foot of the Bay Bridge here, hissing color presses stamp the likenesses of Madonna, New Kids on the Block, M. C. Hammer and other pop stars on thousands of T-shirts. On another floor, workers stock hats, buttons and posters with the images and logos of performers like Janet Jackson and Led Zeppelin, readying them for concert halls and stores around the world.
