The L.A. logo featured on Getty's newest accessories and apparel collaboration was designed and rendered by Prime_K2S, a founding father of stylized street-lettering unique to the City of Angels. Born Jose Reza in L.A.'s Pico-Union district, Prime's early geometric "calligraffiti" was known locally as Cholo script and soon became associated with tagging one's turf.

Here, Prime's cursive L.A. instead adorns the cover of the Getty Graffiti Black Book, which bound together 143 artworks on paper by prominent "graffiti" and tattoo art-writing crews throughout Los Angeles. The artists produced and donated their work in response to viewing rare books at the Getty Research Institute from centuries past.

Among the rare books was a 16th Century manuscript, called Liber amicorum (Latin for "Book of Friends"). It inspired the artists to invent another title for the book that represented their artistic collaboration, LA Liber amicorum, for it bound together the work of rival crews into a book of friends which Prime was asked to design a cover befitting the sentiment.
