UNSUNG HEROES OF ILLUSTRATION 87 HD 1080p

It's been a while since the last unsung heroes instalment, and although I'm well aware they don't attract anything like as many views as others I have no intention of giving up on these lesser known talents as long as there are more to cover. And there are many.
So here, in order of appearance, are E. T Reed, Raphael Kirchner, Miska and Maud Petersham, and Josef Fenneker.
