Reproduced here are two dozen contemporary images—photographs, engravings from photographs, an oil painting, and one printed document—chiefly of Clemens’s immediate family, friends, or close associates during the period of these letters. Several of the photographs have not been published before.
Immediately following these documents are photographic facsimiles of nine complete letters in Clemens’s holograph, a representative selection. We reproduce these documents partly for their inherent interest, and partly to afford the reader a chance to see for himself what details of the original the transcription includes, and how, as well as what it omits. Because of the imperfect nature of facsimiles, close comparison with the transcription will almost certainly turn up apparent discrepancies between the two. The textual commentaries for all nine letters therefore undertake to resolve such differences and to give a full physical description of the original document.
