’Cartier Roman & Italic’ Final unit values – Carl Dair, 1967

The Linofilm glass grids consisted of film negatives of the alphabet enclosed within a metal frame and were very similar to hot metal fonts. They were severely limited as to the number of characters they could hold, which is why Dair’s designs for the maple leaf and the fleur-de-lis ornaments are crossed out – there simply wasn’t enough room for them on the grid.
