In First Nations cultures of the Pacific Northwest, Orca is represented frequently in visual works, as well as oral traditions. Orcas (Killer Whales) are associated with compassion, strong family bonds, protection, and community. Orcas, who are also called Sea Wolves in some Northwest coast cultures, are revered for their hunting skills and sheer strength. Similar to wolves, Killer Whales live and hunt in packs. The entire family, or pod, will normally stay together for life and work together to feed and raise their young. The moon appears in the mythology of all Northwest coast nations. It is a guide, a protector, a guardian spirit, a timekeeper, and it is associated with transformation. This limited edition silk screen print titled "Killer Whales and Moon" by William Cook was hand produced by the screen printing process. It is the only limited edition printing of this design. The artist has inspected and signed each copy in the edition. The printer has destroyed all trial copies and obliterated the printing stencils.
