OK wait a second, those notes don't look anything like Hemingway... my immediate reaction was: what the hell is that?!?! That is the opposite of what I would expect from a perfume named after the one of the most badass man of letters ever born.
It might actually be genius. For example, think back to the 30s and 40s: a sort of sweet, almost "Old Spice" like scent. That is what I imagine they must be going for. Something that doesn't just take our ideas about what a "man" ought to smell like now, but using the past to reconfigure our current conception of masculinity....
One thing that I notice right away is the prominent black pepper note. It's my understanding that Hemingway actually wore Krigler America One, which can be seen here: http://www.basenotes.net/products/krigler-america-one. Interestingly, this was also a black pepper scent with some citrus-like top notes.
