Julia can be a succesful model but that doesn't mean that she's famous,in terms of celebritiness she's a nobody, she simply doesn't make the cut along with Claudia, a model who was more than a Top or Supermodel, she is a pop icon.
And I have never considered Julia a good model, she is young but very blah, completely boring and zero versatile, isn't there a good young German model?
you don't have to be a celebrity to take a good picture and be one of the most successful german models... just because some girls are supermodels doesn't make them look better the cover doesn't say anything about supermodels, it's about german models, which they all are... and I believe julia did several interviews and attended award ceremonie in germany so i guess people interested in show business have heard of her.
Funny that you should mention the boring and very blah thing, that's exactly how i feel about linda evangelista or stephany semour, to name a few but i'm not here to start a debate, i think it's a good, classic cover and i'm happy Julia's on it
