This article by H&FJ has been circling around lately. I stumbled upon it first via my friend Winslow.. and then I’ve been seeing it all around the inter-webs lately. Its a great little article and is insightful and encouraging to those wanting to produce good typography. I was always told in college “no more than three fonts on a page ever!” but in reality, that rule is meerly a giudeline and as you can see, there can be lots of fonts combined and it still look spectacular. enjoy the article!
