When Hawkeye and BJ are in the office trying to get a movie on the wall behind the guy sitting at the desk are a bunch of photos and one is a photo of John Wayne from a western he did in the 60's. So how is it that photos from the 60's are hanging in an office of a program that is suppose to take place in the early 50's. Did the Duke go back in time and do a movie from the 60's just so the people from M*A*S*H could hang it on the wall and see if we viewers would notice the mistake they did? Well we are a little smarter than that, also in another episode Radar says a line from another Wayne movie McClintock which was also made in the 60's.
