A promotional booklet describing the many advantage of the Ludlow Typograph, a noncomposing linecaster, over traditional hand-setting of letterpress printing type. No date, but almost certainly published between the late 1930s and the mid 1950s; it is clearly much earlier than the circa 1960 edition at http://www.archive.org/details/SomeReasonsPrintersPreferLudlowCirca1960 This present edition is distinguished externally by its blue cover.
