American Red Cross on Choice Classic Radio Detectives | Old Time Radio

In the fight against an old enemy, polio, medical research has armed us with a powerful new weapon, gamma globulin. Used soon enough, it can prevent the paralyzing effects of polio. But first, you must furnish the raw material, blood. Doctors urgently need your donation of blood to make gamma globulin. So call the Red Cross. Please don't put it off. It's too important. Call the Red Cross tomorrow and make an appointment to give blood.
