Down the Santa Fe Trail and Into Mexico

No book-club edition documented. The "first thus" traps are all later reissues that add editorial matter: the Yale Western Americana Paperbound reissue (series number Yw-3) with a new introduction by Howard R. Lamar; the Bison Books / University of Nebraska Press paperback (ISBN 9780803281161); and the Yale reissue of 2003 (ISBN 9780300094671). Any ISBN, any series designation, wrappers, or the presence of the Lamar introduction identifies a later book rather than the 1926 first.
