string constant description = "Carlos Marcial's artwork marries the real and hyperreal, alluding to Jean Baudrillard's theories of simulacrum and hyperreality. Using AI, he conducts a dialogue with a digital version of Jean-Michel Basquiat, presenting an imitation with no original.\\n\\nThis artwork, modeled on an 80s photograph, crafts a non-existent moment, intertwining reality and representation. Marcial highlights his solitary role in creating this illusion, merging AI and human creativity in a post-truth era that redefines art.\\n\\nConcisely, this piece urges us to reassess our perceptions and acknowledge the role of AI in reimagining art.\\n\\nTechnology: this collection is composed of True Phygital NFTs powered by Causality, a middleware for phygital connections.
