This is the Standards deck in gold from Art of Play. The tuck is beautiful and the cards handle like a dream. The gold version was never released, and only came in the boxed set.
Here is what Art of Play has to say about this deck:
"Inspired by nineteenth-century British opulence, an era of elegance unsurpassed, Standards premium playing cards redefine luxury at the card table. Produced by Art of Play in collaboration with Kevin Cantrell Studio and crafted with meticulous attention to detail.
Printed by The United States Playing Card Company on our proprietary thin-stock developed for cardists."
