7-up bottle: age?

[Uncola]

Hello, I'm posting this in the soda bottle part (was in the new additions part), and I'm just wondering on the age of this one. It has the slogan "You Like It...It Likes You" on it, but there's no labels on it, it's just all green.

BTW, here's the link to the other thread.
