London? : ca. 1761 . Broadside, consisting of a chart for day and month and a table coding each year between 1761 and 1856; light spotting, very good. After finding the letter associated with the given year, one matches that to the month, and the intersection of the two will tell you the day of the week that the first of the month lands on. One can then compare the date chart below this to move the relative spaces required to find where a subsequent day might land from there. Item #69411
