Vintage 1961 Blond flocked hair Ken doll

Vintage 1961 blonde flocked hair Ken doll in original red shorts. The right foot has Japan marked on it and the right butt has "Ken, pate pend MCMLX by Mattel Inc" and a "6" on the other side. He has some normal wear for his age which includes a scratched eyebrow and of course his natural wear on the flocked hair. The right arm swings freely more than the left. There are some marks that look like it might have been ink. I don't want to damage it but have tried cleaning it with soap. the stand is not included
