The Strategic Scientific Reserve Brooklyn Facility, publicly known as Brooklyn Antiques, was a secret facility hidden in an antique shop and run by the Strategic Scientific Reserve during World War II, in order to develop Project Rebirth.
Steve Rogers returned to New York City accompanied by Agent Peggy Carter of the Strategic Scientific Reserve to a secret laboratory, in order to become the first test subject of Project Rebirth.
Rogers and Carter arrived to an antique store, that served as entrance to the laboratory, where Abraham Erskine greeted Rogers, and Colonel Chester Phillips attended Senator Brandt and Fred Clemson of the Department of State.
