Street photographer Ricky Powell has some new t-shirts he’s dropping and in this clip, he gives some background about one of the designs featuring Mike Tyson and explains how the jubilant boxer once put him in a headlock at the Palladium in 1986 and posed for a photograph thinking that that Powell was one of the Beastie Boys.

Ricky kept insisting he wasn’t, but the champ wouldn’t back down, so finally he gave in and told him he’s Ad-Rock. (Story begins at :47 mark.)

Powell says this photo was taken the night after Mike Tyson’s infamous street battle with Mitch “Blood” Green” in front of Dapper Dan’s in Harlem.
