I'm afraid that Northrup's book is just a bit too expensive for me but I would like to have a look at some photos of Twain at Saranac. Actually, I received a query from a visitor to Twain's Geography regarding photos from a family photo album he has. He is of the family of Seth Thomas, the famous watch-maker, and has an album of the family vacationing in the area. There is a gentleman in some of the photos that look like Twain and I would like to compare them. I don't believe there is a match but the only shot of Mark Twain I've seen is a thumbnail for promoting "With Pen and Camera". -- /Unaffiliated Geographer and Twain aficionado/
