Mosler - BX

Mosler is a heavy, professional grade slab-serif face that works wonders in urban, industrial environments, such as this sample. It's also awesome for athletic type treatments.

Also, remember you can "Pay with a Tweet" for a limited time, the first 150 people that do so will receive a free copy of the lightest weight, "Safe". I think there are only about 60 spots left for that, so get on it quick!
