@Ahzrab - glad you're enjoying the spoilers revealed so far.
@Blargg - Correct - the art is a mix of Deadlands RPG art and from AEG's production.
This is intentional - PEG specifically tasked PBE with 'bringing the world of Deadlands to Doomtown: Reloaded'.
1) DT:R's shining a light on iconic artworks, characters, and settings is part of the Deadlands 20th anniversary year/celebration.
2) This serves notice that Doomtown now occupies a canonical role and interacts with the larger world of Deadlands, its characters, locations, and accoutrements.
BTW - in terms of 'consistent look and feel,' we are DELIGHTED to bring the Servitors of the Reckoners to Doomtown via reproducing the amazing cover artwork of DanieL Rudnicki.
