Uneeda Biscuit
Why erect a big ol' billboard when you can just paint your advertisement on the side of a building. For decades people have been exposed to this Uneeda Biscuit advertisement. I am guessing that if Uneeda Bicuits are still available today they cost a bit more than five cents. Nevertheless, the National Biscuit Company is still shouting out that Uneeda Biscuit!
