Huh? Quick search shows that Oliver Tree is 30 years old, so birth year ~1994 or so. The jazz design came out in 1992 and was widely available through the early 2000s, by solo cup after they purchased it from sweetheart cup in 2004... I really don't see how he shouldn't know where the design came from, but regardless it's become a pop culture/nostalgia symbol because it's just a good, widely recognizable design. What else does he need to know?
