That's what Warner Brothers did when they released the Looney Tunes Golden Collection DVD sets. There were several cartoons back in the 1930s and 1940s that had negative racial stereotypes and mature themes (war, violence, peril, sex, etc.), but there was a disclaimer on each DVD that went like this:
"The cartoons you are about to see are products of their time. They may depict some of the ethnic and racial prejudices that were commonplace in American society. These depictions were wrong then and are wrong today. While the following does not represent the Warner Brothers view of today's society, these cartoons are being presented as they were originally created, because to do otherwise would be the same as claiming these prejudices never existed."
