Cawy Watermelon Soda

Originally produced in Cuba, Now in Miami, Florida since 1959 - Supposedly very popular in the Caribbean - Cawy Bottling produces quite a few other flavors and brands that I've never heard of.

From what I understand this is the can you would buy if you were buying it in the Caribbean. After moving to the U.S. the company started producing the majority of this flavor in the can pictured at the bottom. This is just what I saw on several comment threads about the product.
