Ace Tattooing Co is California's oldest continuously operating tattoo shop, founded in 1947 as a downtown parlor and moved to its current 5058 Newport Avenue location above a taco shop in the 1980s. The shop's mid-century lineage includes a 1970s period that contributed to the fusion of traditional American and Japanese tattoo styles, a pedigree that predates every other OB tattoo shop including Last Days Tattoo Parlor, which opened on Newport Avenue in 2010. The current artist bench covers black-and-grey, Japanese, traditional American, lettering, new-school, and biomechanical work, with cover-ups a named passion specialty of the owner. The second-floor deck overlooking the Pacific means tattoo sessions frequently run with the windows ajar and ocean breeze rolling through — a setup almost unique to the shop because of its end-of-Newport position steps from the OB Pier. Newport Avenue tattoo-plus-piercing pairings cross-refer to Apogee Body Piercing three doors up — clients running a full torso tattoo session will stack a nipple, septum, or ear piercing project within the month-long healing window of the larger tattoo. The signature project type is the cover-up tattoo — reworking faded or regretted ink into a new design — which requires multi-session consultations to redesign color saturation, line thickness, and composition around the underlying piece.
