The deck is free for anyone to download and use. It includes 384 cards and it is estimated that 200 basic hand signs are needed to communicate this language effectively. The button script will randomly shuffle the cards, but the deck can also be added to the scene without the button. Using the scripts for different deck cards is also allowed, just be sure to mention the deck name in the description for sales. PISL (Also Known as "Hand Talk" or Plains Indian Sign Language) was a once widely used sign language used across various Native American Plains tribes to communicate pass inter-tribal language barriers. Tribes would have one or a few members who could communicate in this language, and they'd serve as translators with other Handtalkers for different tribes that spoke other languages. Due to US boarding school policies designed to erase native languages, PISL is a critically endangered language with modern tribal nations working hard to preserve as much of it as possible. This deck is meant to raise awareness of the language while helping digitize language preservation. More information about the language can be found here: https://www.youtube.com/watch?v=s1-StAlw3aE. The images for this deck come from a Public Domain book written by William Tomkins published in 1926.

If you'd like to support a current author and cultural educator who works to preserve PISL, Mike Pahsetopah's "Talking with Hands" is a newly published book that promotes his PISL preservation works. Its better to buy it at bookshop.org, so that he gets a greater commission than from Amazon: https://bookshop.org/p/books/talking-with-hands-everything-you-need-to-start-learning-native-american-hand-talk-a-complete-beginner-s-guide-with-over-200-words-and-mike-pahsetopah/19632789?ean=9781577153665&next=t The images in the back of each card are from the Lakota People's Law Project (LPLP). A nonprofit advocacy organization dedicated to defending the rights of Native American families, land preservation, and advancing civil protections of Native Americans through political and legal activism. The Logo was selected in light of the organization's recent success of shutting down the infamous Detention Facility in Florida, also known as "Alligator Alcatraz." Working together with the Miccosukee Tribe and several environmental groups, Lakota Law supported a joint lawsuit that led to a federal judge halting construction, transferring detainees, and ultimately removing the facility’s infrastructure.
