I agree with a lot of the points made by Lee and Tag_jorrit. I generally look for unambiguous symbols (except in a couple of exceptions), and that's what I'd strongly recommend for a first deck.
But it doesn't have to be "antique art". One of my favorite decks is the Zingdoodle deck (available from the artist, Rootweaver, on Etsy). The symbols are clear, simple, and unambiguous, but rendered in a much more modern, colorful, fun style.
The only tiny quibble I have with that deck -- and it truly is a *tiny* quibble -- is the Garden card, which looks to me more like a flower garden than a place to socialize.
I recently got a Game of Hope reproduction deck. I was really interested in seeing how the original images relate to the current meanings. For the most part, I think it's pretty clear. The one exception is the Birds card, which shows a single bird and, therefore, isn't quite as clearly about "communication" to me. But I can still see it, because of the general idea of birdsong.
There are also a couple of cards that I think are interesting in light of modern interpretations.
The Fox card shows a fox stalking a chicken -- which, to me, evokes the idea of doing what you need to do to survive and provide for your family. (Although I can certainly also see the interpretation of stealth.)
The Tree card shows 3 trees, rather than 1. They look to me like 2 evergreens and 1 deciduous tree.
The Mice card shows a single mouse -- but it's on a table, nibbling on some kind of people-food (bread or meat, maybe). So I can still see the interpretation of loss.
The Cloud card does not have obvious lighter and darker sides, like the clouds on many of the more recent decks do.
Overall, though, going back to the original or to a deck that represents the original symbols faithfully, regardless of the style of art, is very important while you're learning.
