What font is used in this logo?
Here is logo in the footer of this page.
Looks a little like URW Linear Ultra Bold, but the 'A' is slightly different.
It's a very basic typeface, but I love how wide and solid it is. Also, similar fonts work too.
Actually, MoMA has their own official typeface, it is inspired by Franklin Gothic. At one point the museum used Franklin Gothic, but currently they use their own MoMA Gothic that was developed by their team of designers.
