Mosbaugh Catalog Section 9, Medical Seals: Ray Mosbaugh wrote the All Fund Catalog which lists US fundraising seals issued for causes other than TB & Red Cross, and is divided into sections. Section 9 is devoted to medical seals. They were generally intended to be used on mail, as a way of advertising support of the charity. Medical seals are identified by Mosbaugh's Section 9 catalog numbers. |
