Before you buy
In the US the game was sold only with a blue label, so a red-label copy sold as American is actually European. The European cart is far cheaper than the US one, both loose and complete. For a copy at this price, ask for a photo of the board and compare it with the board listed on this page. Ask also for the manual to be shown if you pay a complete-copy price.
