This has to be one of the finest Assassin's Creed-related items ever produced. This is a handcrafted flag that was made using the finest, heavyweight cotton.
It features densely embroidered stars and AC logo; sewn stripes and hems; and a brilliant color combination that gives the flag an aged/weathered look and feel. It looks like it came right out of the colonial era. 
If that weren't enough, the flag comes packed in a presentation case that's made of real wood and features a real fire branded AC logo. Rounding out the whole package is a beautifully detailed letter written by a top Ubisoft exec. 
These flags are rare, make no mistake about it. This isn't the cheapy flag that will come packed in the CE version of the ACIII game. Instead, flags like this one were given only to select members of the press, retail partners, and they were likely also handed out internally within Ubisoft. 
Fact is, no one really knows how many of these flags exist. I have, however, done a bit of research and as of today, I have personally been able to document a grand total of 14 of these flags (including the flag in this listing.)
I found that, for instance, the offices of Giant Bomb, EGM, and Destructoid were each sent one of these flags. Again, that's not to say that only 14 flags exist. In fact, there are likely many more of these out there; but in all likelihood, the overall amount of these in existence is probably relatively low. I wouldn't be surprised if there are considerably fewer than 100 of these out there. I wouldn't even be surprised if only 50 or fewer of these exist. Like I said, I've looked long and hard for these flags, and so far I've only found 14 of them.
I would be remiss not to mention the sheer size of the flag. While I don't have the exact dimensions, I will say that the flag is quite large. I'd say that it's close to the same size of any modern American flag you see waving atop flagpoles in front of schools, government buildings, and stadiums.
I can't stress enough how awesome and important a piece this is. If you call yourself a serious AC collector (or collector of fine videogame memorabilia in general), then you really need one of these beauties in your collection.
