Any idea what the font is used on this 1984 George Orwell book cover?


It must be http://Compacta (Light) by Fred Lambert [1963] + the vertical line

Very creative cover. Love the domineering eye, barb ware and communist symbols as expressions of the theme of 1984. First time I have seen a stencil version of Compacta. Found a previous thread showing another use of the same idea

Looks like a stencil version of Compacta. Manually?

Thanks all 3.
Compacta light it is. I was hoping a stencil version existed but I guess it was added manually.
