Sumerian Cuneiform / Anti-Capitalist Mentality

In the Mises’ edition of LvM’s ‘The Anti-Capitalist Mentality,’ a set of 2 symbols covers the inside of the front and back covers. I’ve been told that it’s Sumerian Cuneiform, but does anyone know what those symbols are / the name of those symbols?

Thanks.

I think it’s this one.

Edit: the term is said to be related to the king Urukagina.
