In Search of the Mansion Key Litho

As I discussed in my previous post All About Key Lithos, as far as I can tell the Magic Key Mansion was sold to the public without a litho for its key.  However, I was looking through the pages of the 1989 Fisher Price Toy Fair catalog and I noticed this image:

If you look very closely at the key in the girl's hand, you'll see that it does have a litho.  I tried to get a closer look, but it is impossible to tell exactly what the litho looks like.  However, it doesn't look to me like any known litho from another set.

Obviously, since the mansion in the photo isn't the same as the one sold in stores (it has different colored parts and the gingerbread trim has actual holes in it) this is NOT proof that a litho for the Mansion ever existed.  Still it gives one hope, doesn't it?  Maybe someday I'll run across a Mansion key that actually has a litho.  I haven't given up yet.  Let me know if you see one somewhere!
