Hello Headline is a bold and friendly typeface designed specifically (believe it or not) for headlines. All of the letters are chunky and rounded, which is probably the reason why they are visible from afar. And I mean, really, really afar. The overall feel of the typeface is meant to be very casual and affable, so it is great for businesses that are fun, outgoing and sincere.
