I've looked at
geneva
arial
helvetica
futura
and the lowercase 'a' does not look close at all.
thanks if you can help.
um ... which lowercase "a"?
If I check with the american site
http://www.mcdonalds.com/
I just get to see "I'm lovin' it" in a font that could be almost
everything but as a guess I'd say Helvetica- or Akzidenz Grotesk- bold.
The font used on
http://www.mcdonalds.com/corp.html
for "McDonald's Corporation" looks like a DIN-Mittelschrift to me.
You may take a look for yourself:
