Love 'em or hate 'em (in New York City they nearly banned them after a blind man tripped over an ill placed sign), sandwich signs are a tried and true method of attracting customers. They can be used in place of blade signs to catch pedestrian/motorist's attention. Eye-catching sandwich signs are an effective (when legal, of course!) way to draw customers into a store. Here are some examples of sandwich signs across the nation (Chicago, Grand Rapids, Queens and Brooklyn). I tend to think that simple chalk sandwich signs are the best solution, but for the more ambitious, creative painted signs really provide a 'wow' factor. But like all things, too much of a good thing can also result in visual clutter...as shown in one of the images below.
