Well it's not quite pocket size, but much smaller than I was expecting. This is a 1967 edition, by Sierra Club, with unsatisfactory printing. I've read that Mr. Porter went to a lot of trouble making sure the reproduction quality was of the best standard possible. Did they print this one to spite him? He must have been aware of it. The dimensions are 24x16cm with faded and fuzzy reproductions in a book with no visible browning and in good cosmetic condition. I also have 'Appalachian Wilderness', in much worse condition with browning, 1975 printing and the colour and detail is better than some of my books printed this decade. Does anyone have this version of 'In Wildness...' and if so, is the bigger book much better - before I send this one back? Thanks very much.
