Those are some great scans!
I can understand why you wouldn't want to sell the cards as they are nice pieces.
In response to Rocket Surgeon's comments, I've been an Indiana Jones fan since early '84 when I caught a re-release of Raiders of the Lost Ark at my local cinema. I convinced my parents to get me Raiders on VHS for my birthday and then I proceeded to watch it over 20 times that summer. This also coincided with the release of Temple of Doom which made for a great summer!
I have a fairly decent collection which I've gathered since '84. The collection covers most areas and because of this I have quite a few areas where I need to complete.
I've recently bought a house with enough room to start displaying some of the collection and I'm now trying to sort it out and identify which areas I need to complete. The smith's promotion is one of those areas.
Below are a couple of pictures of the Lao Che's Double Cross play n' wipe cards that I have along with the Smith's mail-away poster.
