Wanted poster
Wanted Posters are featured in Assassin's Creed II as part of the Notoriety system introduced in the game, an upgrade to the Social Stealth system. Once Ezio reaches a minimum of 1% Notoriety, Wanted Posters are featured on the map as locations of importance. Wanted Posters can be torn down by simply interacting with them. Each Wanted Poster torn down reduces Ezio's Notoriety by 25%. Strangely, many Wanted Posters are in unlikely and not easily viewable locations, such as balcony's or the wall of a tower, essentially defeating the purpose of publicly displaying Ezio. If guards are nearby and see Ezio tearing down a Wanted Poster, the notoriety meter will increase by a small amount, so be careful when removing a poster.
The Wanted Poster spawn locations aren't at all as random as one might think. If you tear down one of the Wanted Posters, and then improve your notoritey close by, the Wanted Poster is likely to simply re-appear in the same location.
