This geometric shape might look like the kind of floral decoration old-time printers used to separate blocks of text, but no – it’s from a patent. Specifically, the patent category of “Brassieres with stiffening or bust-forming inserts.” Other illustrations in the patent application show that it’s a disconcertingly perfect dome, like the roof of the Hagia Sophia or St. Paul’s cathedral. Seth Wheeler, of Albany, New York, was granted the patent on June 11, 1889, for bosom pads formed of “a single piece of paper, stiffened linen, or cloth-covered paper stamped or blocked into the desired shape” with corrugations to “add materially to the strength of the form.”
