Humour Tin Sign: If there is one beverage that is guaranteed to give you a little pick me up any time of the day or night, it is coffee, and this comical retro style tin sign highlights one of its many benefits. Against a cute blue and white polka dot background, a young woman stands with a cup of coffee in her hand and a smile on her face with the words 'Drink coffee. Do stupid things faster with more energy' floating above. So why not treat yourself to the perfect mid-morning perk and hang this humorous tin sign at home or in the work place.
