Invention Card(s)

The Guide states that the first invention card is above the picture on the safe.
I've clicked all over that area but nothing is there.

If I remember, it was above and a bit to the right.
Thing is, those cards morph from invention cards to nothing (as far as I can see)
and will not open unless the card outline is visible.

Hope you fin them....I have been finding the info on them quite interesting
