Advertisement for 'De Witt's Kidney and Bladder Pills'

De Witt's Kidney and Bladder Pills were produced by a firm founded in 1912 by EC De Witt, with branches at 160-162 Superior Street, Chicago and in New York. It became part of the CB Fleet Group in 1990, whose UK operation is currently based in Runcorn, Cheshire where they still manufacture toiletries, skin care products and pharmaceutical products. Some of their other popular medicines manufactured at the time were 'DeWitt's Cough Syrup Bottle', 'DeWitt's Headache Tablets', 'DeWitt's Rheumatic Pills' and 'Dewitt's Man-Zan' for haemorrhoids.
The card would most likely have hung in a shop window, on a wall, or been placed with a display of the product. It is printed in black and pale blue on white card showing a rather pained looking Mr A Sparrow (of Tonypandy, Wales) who had been suffering from bladder calculi (or stones) but claimed to have passed one a mere two days after taking DeWitt's pills.
