Like I am using either the standard Rider tarot or the Tarot of Marseilles which both probably are a bit outdated, lol...
Not the Wright brothers, also not Howard Hughes. Earlier.
Checked your links. "Regeneration machine" still looks kinda timeless to me.
Enjoy your break, and thank you for playing. I learned a lot through this game, and not only about tarot cards (with which I probably never will be a master, lol...)
See you later.

EDIT: There also is something about that "engineer", how he is standing in front of the machine, about the energy... which could be seen as timeless.

EDIT: Just realized... when seen in a more "symbolic" way, your cards make so much sense. The "airship", yes... as a symbol, not so much as something related to a specific time or to a solid ship.
