What's the difference between the claims made on this card and the last one? Which one do you think is older?
While this card - which is more recent than the previous one - promotes its product for an unlikely combination of ailments, the manufacturers do not claim to cure anything. Instead, they just claim that their product is "invaluable for" various problems.
In the first decade of the 1900s, governments began to pass legislation controlling the claims that could be made for patent and over-the-counter medicines.
