Publishers Victor Gollancz introduced their yellow jacket shortly after the firm was founded, and almost all their publications between the 1920s and 1980s were yellow jacketed.  These highly distinctive, and now niche collectable, jackets, are easily recognised from their plain yellow covers and stylised use of fonts in black and magenta.
