Thought I'd link to this article I've just made for your viewing pleasure. It's a comparison of the maps used in the traveling montages in all four Indy films (plus the Young Indy series).
Anal retentive? Surely! But it's also actually rather interesting from my perspective.
Hmm, really? What kind of error message are you getting?
Anyways: Raiders and Last Crusade use one map style, Temple of Doom uses another, and Crystal Skull uses a blend of the Raiders/LC and ToD styles. Also, the Young Indy maps are all over the place style-wise, sometimes even within the same episode.
