While the Dallas of tomorrow may be crashing toward an all-digital internet of things, luckily there will remain holdouts to remind us of the power and beauty of old-school analog craftsmanship. Count Sean Starr and his wife, Kayleigh, among them. Their Starr Studios in Denton specializes in hand-painted and gold-leafed signs, each a unique and carefully crafted work that only human minds and hands can create — at least for now. You may have seen the couple's work on the cover of the Toadies album Heretics, for Shinola Detroit, for Rahr & Sons Brewing Co. or on the bright red and gold old-style storefront at J. Hall & Co. Gentleman Tattooers, 1709 Lamar St. "Sign painters" understates what the Starrs do. They are artists, and as proof of that. they recently opened a gallery to show their work, as well as curated shows by other artists, in the Design District.
