Move over, Ken. Don Draper is coming into Barbie's world. Following three successful seasons of 'Mad Men,' Mattel plans to bring out versions of Barbie and Ken styled after four of the show's characters. The collectors' series will include Don Draper, the show's leading man; his wife, Betty; his colleague at the Sterling Cooper agency, Roger Sterling; and Joan Holloway, the agency's office manager who was Roger's mistress, NY Times reports. The dolls are scheduled to be released in July to promote the fourth season of 'Mad Men,' which will begin that month on AMC.
