Little did Indy know, but in 1938, Venice was the center of the fighting between the Sicilian Mob and the Poison Fist of the Pacific Rim (also know as the Japanese Mafia) in what would later be know as the Sicilian-Japanese Mob Wars.

The MOC looks great! I love the way you made, well, everything in it. Are you sure about the accuracy of that historical reference? I can't find anything about that event at that time, or anything on the "Poison Fist".
Dude, I made the whole thing up. I thought it'd be funny to have Indy's adventures abruptly interrupted by a gang of ninja/mobsters.
