The digital Gill Sans Light Shadowed is based on Gill Sans 406 Shadow AKA Gill Sans Shadow No.1 (1936). Stephenson Blake offered a wood type version named Shadow Sans. Ludlow’s Umbra (1935) is very similar. There is also the bolder Gill Sans 408 Shadow AKA Gill Sans Shadow No.2 (1936, undigitized). Gill Sans 338 Shadow AKA Gill Sans Shadow No.3 is an earlier release (1932), to be combined with the caps from the regular 262 series for chromatic effect.
