This is Alonzo Ames Miner, one of the Universalist bigshots of the nineteenth century, and was the second president of Tufts. I think it is from a collection of sermons I have in storage, c. 1856, but don't quote me on that date. But that would make Miner about forty-one, which looks right.

I think it helps when you know what some of these people looked like. I have a whole bunch of these, which I'll pull out as needed. Feel free to grab the image for your use -- but if you grab it, store it on your host -- and a link back would be appreciated.
