Steamtown is a sans serif type family of three weights and four styles. It is based on geometric forms, so it is a clear and straightforward typeface. It has an industrial feel and also resembles street signage. It has four styles; Clean, Rough, Print and Press. The Rough style has rough edges, Print has a subtle texture and Press has a heavy letter-press texture. Rough, Print and Press styles have two sets of upper- and lowercases.
You can manually alternate the two sets of upper- and lowercases or you can enable the Contextual Alternates OpenType feature to automatically cycle these two sets of letters.
