Earlier Wednesday, Lady Gaga posed for a 20- by 24-inch Polaroid picture, which will remain on permanent display at the museum. This past January, Gaga was named creative director for Polaroid corporation, which was originally founded in Cambridge in 1937.Although Gaga left before the official museum event began, Polaroid’s corporate president, CEO, chief marketing officer, and the museum’s curator each addressed a crowd of press and pre-selected MIT students regarding their plans for the Polaroid Archive. The archive was donated to the museum’s permanent collection earlier this year, and includes roughly 10,000 items, spanning roughly 70 years of Polaroid technological history.
