Dunkin’ Donuts is receiving scrutiny after an ad surfaced on a train in Thailand of a model in blackface, her lips painted bright pink, advertising their “charcoal donut.” This, of course, is argued by some as reminiscent of the blackface minstrelsy of the 19th and 20th centuries but, for others, it is nothing more than a “marketing strategy.” In Thailand, however, the use of racial stereotypes is oddly common in the promotion and sell of products.
