The "U and I" bottle is about 1948 vintage.
Patio Diet Cola was a brand of diet soda introduced by Pepsi in 1963. It was created in response to Diet Rite Cola, which was the first diet cola on the market. In 1964, Patio released orange, grape, and root beer flavors. Patio sodas were available in the cold-bottle market: grocery and mom-and-pop stores. In 1964, the line became Diet Pepsi.

The Patio is only $1-2, The Kick-a-poo can be $10-20 in great condition and the U and I is only a $1-4. If you like them it really doesn't matter, if you bought them for resale you overpaid unless you find someone who doesn't know their value....Jim
