Beginning in January, 1932, Becker, at the request of then-editor E. Thomas Kelly, supplied SIGNS of the Times magazine's new Art and Design section with an alphabet a month, a project predicted to last only two years. Misjuding the popularity of the "series," it instead ran for 27 years, ending finally two months before Becker's death in 1959, for a grand total of 320 alphabets, a nearly perfect, uninterrupted run. In late 1941, almost ten years after the first alphabet was published, 100 of those alphabets were compiled and published in bookform under the title, "100 Alphabets," by Alf R. Becker.
As published in June, 1937, this is the description that accompanied Becker's 66th alphabet, Neonline:
“NEONLINE BLOCK, alphabet No. 66 in Alf R. Becker’s SIGNS of the Times series, is a very bold, modern style for feature display lettering. Care should be taken in the laying out of this alphabet, and every letter should be made as bold as possible...”
