I saw this on another site and had to look at it a few times. It's a promotional poster from the 50's for the oral polio vaccine. Notice that the third selling point is "prevents polio"... Do I really give a damn how it tastes and how fast it works if it, y'know, prevents freakin' polio? Isn't that selling point enough? If a cure for cancer was developed tomorrow, does anyone really believe that it wouldn't be used if it didn't come in grape flavor?
