In the dark ages, brewsters, women who brewed beer, had some rather odd advertising methods. To be noticed in crowded markets, they tended to wear tall, pointed hats. To indicate when a brew was ready, broomsticks would be placed in the doorways of alehouses. Images of frothing cauldrons full of ready product and six-sided stars to indicate the quality of the brew also abounded. Lastly, out of manifest necessity, cats would be kept in the brewhouses to protect the grains from mice.
