The portfolio of Boston's Alphabet Arm Design is full of great retro logos, harkening back to the days of sophisticated typefaces, but also designs with a street art flair.

Standout branding examples include: the two-tone Cable Car Cinema & Cafe logo, which updates industrial-era visual elements with an sophisticated identity; Empire Attire's elegant and bold cypher, a logo that would look equally good on a monogrammed tie or an alley wall; and Matisyahu's distressed type logo that would make the perfect stencil.

Alphabet Arm Design's blog also has some great process work, showing alternative typefaces and pre-vectorized sketches.

My one gripe is that Alphabet Arm Design's company logo is plastered in sticker form on the back of every third street sign in the Boston/Cambridge area. There is a difference between being inspired by street art and trying to become street art through "guerrilla marketing." Leave the street signs to the real sticker artists, please, and continue making your mark with iconic graphic design!
