Two brochures from the Blue Rapids Supply Company of Blue Rapids, Marshall County, Kansas. The brochures are for medical-grade plasters and pumice that could be used by dentists, hospitals, laboratories, orthopedists, and schools. Brochures include prices for different kinds of plaster and for the pumice, as well as shipping/freight prices. The September 1941 brochure includes a drawing of a Jayhawk bird as part of the logo on the front page.
