LL Courier Sans Mono
Lineto · James Goggin · 2001

A sans-serif derived from Courier by removing every serif, first made as a student exercise in 1994 and later rebuilt as a true monospace in 2016.
About
James Goggin created the original as a deadpan riposte to a 'Courier only' brief at Ravensbourne in 1994, simply cutting the serifs from the system font. The first commercial release in 2001 used proportional spacing for visual harmony, but the 2016 redraw restored genuine fixed-width metrics, tying it back to its typewriter origins. Light and Regular weights are offered with italic cuts, and a separate proportional sibling, LL Courier Sans, carries the non-monospaced lineage forward.
Classification
A monospaced sans derived from Courier by removing all serifs, deliberately reconnected to its typewriter roots in the 2016 redraw with true fixed-width spacing.
