Gresham College is presumably named after Sir Thomas Gresham of Gresham's Law that "Bad money drives out good". They seem to be testing this by putting bad publicity (using a picture of working men from the 1900s to illustrate a talk on middle class "Communists" in the 1930s) into circulation to see if it really will drive out good publicity.I would have thought that a formal protest is in order on at least two grounds (1) that it's a photo of working men not "middle class" and (2) that we've always had no association, except for opposition and contempt, with the Communist Party
