2023 Epoch One Promo Cards

Another one of the unexpected things that Ryan sent me was a handful of promos for the 2023 Epoch One cards.  Until I saw these, I had no idea that there were promo versions of Epoch One cards.  Here's the five cards he sent me:

You might be asking yourself, "why is he calling an Epoch One promo card for an event in 2022 a 2023 card?"  That's because the back of the card shows a copyright date of 2023.  All the card backs are identical, except for the photo and team name:

These backs are very similar to those of the "regular" 2023 Epoch One cards:

The big difference on the backs, besides the lack of a card number and the promo information at the bottom of the card, is that the promo cards lack Epoch's watermark.  The fronts, however, look exactly the same as the non-promo version of the card (none of which I have).
