TI large Mystere key variations

It's always interesting how many subtle variations of a key may exist. At first glance, the three keys seem very similar...then the obvious difference on the top key not having arrows catches your eye. Flip them over and you realize that the mag stripe is on oppostie sides of the wording on the bottom keys. I can't wait to get to the TI section of the illustrated guide to show some of the Social House and Spa variations (and to find out about more that are out there that others have found).
