Vintage Electric Corset Baseball T-Shirt

From the original 1883 advertisement: "[These corsets] were constructed on scientific principles, generating an exhilarating, health-giving current to the whole system. Their therapeutic value is unquestioned, and they quickly cure, in a marvelous manner, nervous debility, spinal complaints, rheumatism, paralysis [!], numbness, dyspepsia, liver and kidney troubles, impaired circulation, constipation, and ALL other diseases peculiar to women. They also become, when constantly worn, equalizing agents in all cases of extreme fatness or leanness, by imparting to the system the required amount of 'odic force' which Nature's law demands." (Not to be worn in water, I imagine.)
