Over at National Review online, they have an article by James Robbins on the attacks on U.S. Grant, especially in his second term. The article doesn't do much for me, but what is interesting is the color portrait (I think it's a colored photograph) of Grant on the NRO homepage. Here it is isolated:
There is something about a well-done photograph that really brings historical figures to life. There is a daguerreotype of John Quincy Adams that is the frontispiece of Paul Nagel's biography, John Quincy Adams: A Public Life, A Private Life. I've never seen it anywhere else, and I cannot find it online (Nagel says he got it at Amherst). Something about that portrait--perhaps the clarity, which is remarkable--brings Adams to life.
