I just came across a post (that's a few years old) with the history of some soda can designs :
I'm sad that the "bubbles" so prominent in the 7-Up design (in 1961 and 1980 - 1994) have disappeared.
And I prefer many of the older more simple designs. The 1960s - 1970s have the most of my favorite designs above. I like the 1965 and 1972 Crush cans and the 1990 7-Up can. What do you like?
