Jen sent me a link to this early, portable, folding bathtub, for sale on eBay. From the original advert:
"If you have no bathroom, buy a Mosely Folding Bath Tub", "Don't look around for another house, and "acts well and looks well". An advertisement also notes that the tub is "portable, with self-heating arrangements to heat water at a moments notice. A great convenience and when closed an ornament to any room...". Send two cents, for illustrated catalogue, showing 18 styles of tubs..."
