c1920 San Antonio Texas Quack Medicine Radio Magnetic Nerve Vitalizer with Paperwork Describing Cures. Interesting and rare. Includes prospectus of purposed corporation to distribute this device. So I actually believe this was the salesmans' sample that they used to try to sell the device. In this paper it states their price was $40-$50 in 1919, so they likely never sold any as I can find no evidence of another existing. It cured crippled people, crossed eyed people, all that good stuff. Untested by me. The corners to the box lid are split.
If you're the gullible type please don't buy this expecting it you cure all your ailments. Buy it as a rare piece of Texans, novelty item, quack medicine. Something of that sort, or all of the above and then some.
