Strange Pepsi bottle with double label

[EdsFinds]

I bought this bottle today at an antique shop. It has a strange double lable with both diet Pepsi and normal Pepsi label. I also don't know what the brown stain wrap is. Anyone know anything about it, or have any ideas?

Wow! IF that's a mistake or some kind of company experiment to save money, that's like finding a mistake on a stamp or a coin (maybe not so rare or valuable as such, but)! These are the holy grails of collecting. I mean, where ya gonna find another one like it that survived the times? Great find!
