Depends on what you mean by "original design". If you're talking about decks based on the Game of Hope, which is the origin of the Lenormand deck, there are a couple of reproduction options:
AT member Tag-jorrit did a beautiful reproduction. I have both the regular size and the mini and can attest that they're absolutely fantastic. I don't think that deck is currently listed on her shop, but, if you contact her, she might be able to do a special order for you. That's how I got mine.

(I'm actually looking to sell my mini. PM me if you're interested.)
The other options are:

and

If you mean something else by "original design", you'll need to be more specific. But, regardless, I'd strongly recommend checking Tag's shop (first link given above), as she has many beautiful reproduction decks listed.
