Stilla: The Greatest Numerals
According to Herb Lubalin in the 1975 Second edition of U&lc (Upper and Lowercase magazine), which can now be downloaded as great hi res PDFs from the fonts.com blog. They're up to six issues in what must be a time-consuming endeavor. It's such a great idea and I hope they continue to upload what was a great example of Herb Lubalin's love of typography and contains many gems that don't feature in the book.
The numerals are shown in Stilla, designed by French type designer, François Boltana in 1973. A perfect example of the 'Fat Face' type style. The commercial face differs slightly from the above version which surely must have been hand drawn by Lubalin.
