These are sections F-46 through F-50 of the book of information issued by the Ludlow Typograph Company to its sales force. This particular copy of this book is No. 47, current through 1962. It appears here through the courtesy of its present owner, Jeff Shay. These sections cover the matrix fonts for Ludlow typeface families No. 46 (Greenwich), No. 47 (Samson), No. 48 (Flair), No. 49 (Admiral Script), and No. 50 (Society Text).
Note that Flair is one of the few Ludlow faces which requires a special 40 degre
e italic stick and related equipment.
