It's a piece for Make-A-Wish Metro New York... Rosa is a Make-A-Wish alumnus.
As ABC 7 reports, Rosa, a Bronx native, was born with HIV and spent years in foster care. He was recipient of a "life-changing" Make-A-Wish trip to Disney World at age 7.
"What kid doesn't want to go to Disney World," he told the station. "It let me know there was more out in the world than the small space I was occupying."
This space on Avenue A is curated by the Lisa Project, the 501c3 public art charity that Rosa founded with his husband Wayne.
