Point of order, an effigy by definition would be a dummy/representation of the thing that you then symbolically destroy.

As in, you make an effigy of Mussolini out of cloth and stuffing and burn it in a protest before lining him against a wall, killing him, and defiling his corpse. The corpse itself is not an effigy unless you then use that and make it look like Hitler, and then burn the Mussolini-Hitler corpse as an effigy of Hitler, which tbh would have some layers to it and seems like an innovation in effigy technology…
