Sterling Cooper Lets Me Down
As previously mentioned, Rosscott, Inc. is a big fan of Mad Men because it is amazing. I know it has a big following in the design community, probably due to its subject matter. As such, some designerds of my proportion have found a slight flaw: they use Arial in the end credits.
Seems as good of a time as any to point out that The System is 100% Helvetica Neue.
