As you can see, the unknown daguerreian achieved a spot on exposure here. This sixth plate of an unsure young boy is near perfect. As the man set up his camera, he gave the boy a small book to look at. Having recognized the shape and inferring the complete title is “Boston Almanac,” I have just viewed different covers from the 1840s online. Design-wise, it could be the 1842 or 1843 versions, placing the book from a few years before the image was made and the image most likely made in the city. As you can see, it has not been resealed. It retains what are probably the original seals, although I would recommend new glass as it’s a bit dusty. The case is whole and has a nice starburst design.
