As I've mentioned...I kind of HAVE done this experience. I used to run a pop culture store at a popular tourist town. Since I'm a geek, I had a superhero section of tshirts etc. Superman, Batman, Wonder Woman, Spider-Man, Punisher...these t-shirts (mostly just logos...) were recognized instantly. Flash was often pointed at along with the statement "Look, it's Flash Gordon shirts". Green Lantern did not sell...it was a green shirt with the logo...and over and over and over again every day I was asked which superhero it was...and when I said "Green Lantern" I generally got a confused look. I even sold superhero rings...one of them being Green Lantern. Despite the fact that he's the only one that wears a ring, that was the lowest selling ring in my store. No one seemed to know what it represented. This was a VERY busy store with TONS of customers from all over the consumer map of ethnicity, age etc. Green Lantern was simply not recognized very often.
