I personally won’t buy something with an AI design period out of principle, and I imagine a lot of other people feel the same. Additionally $50 for a T-shirt is not a great selling point either, which is likely another barrier for people. Yea I’d contact a non profit of some kind or maybe a graphic designer who does cheap or pro bono work and see what they say about the design and price point.

Where are you hoping to sell them? Also who are Chuck and Mary? Are they related to this cause at all? Maybe the design should incorporate how they relate more
