Courtesy of Chris Lukhaup, he has provided his professional posters for downloads for members. A price is listed so it sorts to the top of the page, but no need to purchase. You can have them printed for your personal use. Please do not distribute to others as this is only authorized for Members of Aquarium Co-Op's YouTube channel. Don't ruin this for everyone, use them for your personal use only, and don't share on social media platforms etc.
