Part of the fun of what I do is learning the design language of a given culture and attempting to create a character, creature, or object that seems like it belongs to a culture even if it never existed. This is one of those instances. I found reference for similar items all over the web, but not quite like these. Additionally, casino games usually call for high value surfaces (like gold) that would traditionally never be used to make, say, a pipe.
These were all created and painted in Photoshop on a Cintiq.
