Impossible 70s typeface?

Does anyone know which font this is? I've seen it many times before. The image is from the mid 70s.

Does a digital version exist? and does anyone have the original sheet?

Any help is highly appreciated!


found out.. it's called Zelek!

Also known as Zelda in Dan Solo's [[|Moderne Alphabets book]]. There are a couple of digitizations [[|in the abfonts archive]].

Some of the fonts at abfonts are not good.
I guess they digitize typefaces without permission. Do you think it’s ok to steal letters designed for football jerseys?
