Excavation Earth: Pretty Boxes & Ancient Artefacts contains two sets of alternate artifact tiles — "Ancient things" and "Things that make noise" — as well as a "Pretty Box" expansion that adds one new artefact of each color, with that artefact being placed on top of the matching black market stack when revealed instead of on the map. This item was a Kickstarter Limited Exclusive included in the Explorer, Envoy, and Collector pledges, and it's labeled "PROMO 01".
