My rule of thumb was that if an image offended a black student because of its visual associations then I would not use it within a discussion. Sometimes it would have been useful to demonstrate what black people have to put up with, but I steered clear. The argument with illustrators was around the Robinson's Gollywog as a brand character and the children's illustrated story Little Black Sambo. I just wasn't doing it.
Standard objections to my reticence (fastidiousness?)
1. haven't you got a sense of humour?
2. Everybody loves Little Black Sambo.
Perhaps the cheerfully obsequious Pullman porter, a last vestige of the Slave days in white travellers' lives, could act as a first point of reference. Douglass Crockwell's image of black graduates for Avondale is unusual for the period (1948).
I couldn't think where else to put the photograph of Barry Goldwater, presidential hopeful and a republican on the right, dressed in war paint as a Smoki Indian. This adds a new and worrying edge to his more bellicose threats of using nuclear weaponry against the Russkies. It is about as persuasive as Peter Sellars' Indian Doctor singing Goodness Gracious Me.
