Last year’s September issue of Vogue was a particularly monumental addition to the pop-culture canon. Not on account of its cover star, Beyoncé, who’d fronted the magazine at least three times before, but for the photographer she chose to have behind the lens: the 24-year-old rising talent Tyler Mitchell, who effectively became the youngest and first black photographer to ever land a Vogue cover commission. As Beyoncé put it in the pages of that issue, “If people in powerful positions continue to hire and cast only hire people who look like them, they will never have a greater understanding of experiences different from their own. They will curate the same art over and over again, and we will all lose.” Two months ago, a photo from Mitchell’s cover shoot was acquired by the Smithsonian National Portrait Gallery.
