I guess as a fellow Trump-disliker I can get ridiculed for posting about his bandage but that is a very funny looking bandage. First, if he had a fairly signficant ear injury there would need to be a vaseline gauze dressing going in all the folds of his ear then compression over the top and behind the ear to compress to keep blood from getting between the skin and the cartilage. That would be a larger dressing and need to be in place for several days.View attachment 5854seriously though, how long must you wear a bandage for an ear injury? and does it have to be this large? Holyfield never wore a bandage!
If there is a minor wound, there doesn't need to be a big square. A small, form fitting dressing would make more sense.
Just like his hair, persona, and everything else, he just does things in strange ways. It would not surprise me if the purpose of the big square dressing was to make it easy to mimic and obvious what you were doing if you did mimic it.
