And we're back to the "present" of March 1939!
It's an interesting complication to have rival bad guys waiting outside the pyramid -- but a really challenging encounter if the Heroes (can I call them heroes in this case?) come out injured or weak.
That King Tut would have a secret cache of magic potions -- including a Potion of Invisibility -- seems comic book plausible, minus the perfume bottles. On the other hand, loading magic potions into a perfume bottle so they can be sprayed on does seem an...intriguing notion. It would be up to the Editor to decide if potions need to be ingested or not.
