This a very odd situation so please read closely.
I have been organizing a community-wide project in the fanbase of a video series where various artists can volunteer to draw and submit their art in the form of tarot cards for a complete deck (any minors 17 and younger who are participating are required to receive their parents written permission to submit their art.) These artists are going to be credited in the form of an included booklet with each deck, which all artists have agreed is adequate.
I have been given written permission from the creator and copyright holder of the video series to run this project and sell the completed deck on the agreed condition that 100% of the profits go to charity. I do not believe I have any need to file a copyright as the source material is not mine, we are simply using it with permission. It should also be noted that this is not going to be sold forever, rather it is a limited edition deck that, once the preorder listing expires, will never be sold again.
As for writing the copyright footer on the physical box, how would I write this out? I've seen online examples such as "© 2020/2021 ExampleName" but I'm unsure if that would transfer to a physical product.
I am also unsure if I should write any copyright information on the listing itself (likely through Etsy, since it's cheaper and more secure). If so, how would I do that?
Any help is appreciated, thank you!
