Most of the cartoon anthologies have that. The Warner Golden Collections are notable, though the label is deserved; one Bugs cartoon in particular has Our Hero sneaking into the South to get to a record carrot crop. He has to get past Yosemite Sam (as a civil war soldier who doesn’t know the war is over) to get there, and at one point Bugs goes into blackface, complete with the “yassuh mastah” routine: “don’ beat me massuh, i be good” etc.

It’s not “Bugs Nips the Nips”, but it’s not much better.

It's not just cartoons. I was listening to a Nero Wolfe audiobook and there was a disclaimer in the preface, talking about how it was written in a different decade before the civil rights movement.

I wonder what disclaimers will be placed on products 50 years from now. "NOTICE: This movie was produced before incandescent light bulbs and internal combustion engines were outlawed. It is not necessary to inform the Green Police of the activities being portrayed." or "RATED NC-17 FOR MILD PORTRAYALS OF MINOR CHRISTIAN ACTIVITY"
