Who Were They?

Here’s the next page in our bowler hat extravaganza, with three more wonderful hats. Or are they new? The bottom left image is a repeat from a previous page with the high bowler hat. The top left and lower right look like the same person at first glance, but are two distinct faces. I imagine if you were looking for a man in a crowd of men wearing these hats it would be difficult to find the exact one you wanted!
