Bonelli team-up is a site dedicated to team-up and crossover of comic book heroes published by Sergio Bonelli Editore
Currently it features gallery of images where two or more Bonelli heroes are appearing. If you have any image thats not available on this site please upload it here
Soon I will publish list of all Bonelli team-ups, crossovers and various references, which will lead foundations for building unofficial Bonelli-verse.
