Fanposter (concatenated noun consisting of Fan and Poster) refers to a community of Fans (supporter) sharing common interests in a particular sport, hobby or genre who want to express their relation within this community by placing themselves on a poster (map) in proximity to others.
The process of stitching photos together can be driven and accomplished by a fan club, a fandom, individual members or by the fan community in a collaborative effort.

The goal of creating a fanposter is to show all or a large portion of devoted fans on one poster which will be presented and seen in a place where many other fans or members have access (hallway of a club house, fanzine, fan webpage).
