To try to keep the coffee aromas in the stores pure, Starbucks banned smoking and asked employees to refrain from wearing perfumes or colognes. Prepared foods were kept covered so customers would smell coffee only. Colorful banners and posters were used to keep the look of Starbucks stores fresh and in keeping with seasons and holidays. Company designers came up with artwork for commuter mugs and T-shirts in different cities that was in keeping with each city's personality (peach-shaped coffee mugs for Atlanta, pictures of Paul Revere for Boston and the Statue of Liberty for New York).
