Because it's original.
well, it's no longer original as soon as do work on a cab, let this be applying replacement sideart or filling holes. for me it is "how can i make a cab look good?", even if this means making minor changes, for example i've never understood the placement of the DK instruction sticker or the position of the dragon's lair sideart - both of them look just horrible in their original position!
but each to his own, how boring would this hobby be without a little controversy?
