One of their artists, "Jules", created an NFT clearly modeled after The Falling Man, a well-known photograph of a man falling from the upper floors of the World Trade Center during the September 11 attacks in New York City. The NFT is also titled Falling Man, and pictures a model in the same position, but wearing an astronaut suit.
Not only is GameStop selling an NFT of the victim of a tragedy, it's a featured image when Googling "GameStop".
