Mrs. Mildred Sellers, nurse, examining a needle under a microscope for imperfections which, though invisible to the naked eye, would be painful to the blood donor into whose vein the needle will be injected. This is only one of many precautions taken to see that donating a pint of blood is a painless process. Everyday 1,500 needles, bottles and rubber tubing attachments leave the Armour laboratories for Red Cross donor centers in Fort Worth, Texas, Dallas, Texas, San Antonio, Texas, and New Orleans, Louisiana. Mrs. Sellers is wearing her nurses uniform and a hair clip.
