About Killer Acid
Killer Acid is the psychedelic art and apparel brand of artist Rob Corradetti, who’s been making paintings, drawings, and weird products for over 25 years. Based in Santa Cruz, California, the brand makes screen printed tshirts, hoodies, stickers, blotter art, home goods, and limited edition prints, all featuring Rob’s signature cartoon psychedelia, dripping with tongue-in-cheek humor and wild colors.
THE ARTIST
Rob Corradetti grew up in suburban Delaware. He started drawing seriously as a teenager, filling notebooks with pen and ink sketches, often at Brandywine Creek State Park or Valley Gardens Park, in the back seat of a friend’s Chrysler New Yorker. Drawing became a way to channel restless teenage energy into something that lasted.
At age 17, in 1994, Rob showed a notebook full of drawings to a local screen print shop owner in Ocean City, Maryland. That connection changed everything. Rob created his first brand, Craggy Sun. With the help of the shop owners, Rob learned the basics of screen printing and came away with a few boxes of t-shirts on Anvil blanks, selling them for $20 out of his car trunk to classmates and local hippies alike.
The foundation of everything Killer Acid would become was laid right there: hand drawn art, screen printed products, sold direct to people who got it.
From there, Rob spent formative years in New York City, soaking up the energy of advertising, comics, and the DIY comics scene centered around Desert Island Comics and Printed Matter. In 2010, he launched Killer Acid, schlepping tubs of t-shirts to craft fairs and book fairs, building a following one print, one shirt at a time.
In 2018 Rob packed up with his wife Sierra, and made for the West Coast; setting up shop in Santa Cruz, California where he methodically began to expand the business with his long time friends.
THE STYLE
Rob describes his work as, “one part hippie, one part punk, one part busted up junk in the trunk.” His art is populated by four eyed cats, smoking birds, grinning mushroom dudes, and all manner of psychedelic creatures; friendly gremlins he calls “docents of the mystical world.” The style blends head shop aesthetics with punk rock energy, rooted in his technicolor coming of age in New York City and sharpened by decades of daily drawing.
THE STUDIO
Killer Acid operates out of a studio in Santa Cruz, California. Rob leads a team of eight, developing everything in house, and shipping products worldwide. The brand focuses on direct to consumer sales through the website, having learned that staying close to the customer produces the best results, for the art and for the people who wear it.
COLLABORATIONS
Over the years, Killer Acid has collaborated with brands and institutions across the stratosphere. Notable partnerships include Santa Cruz Skateboards, Meow Wolf, Liquid Death, Polaroid, The Grateful Dead, Retrospekt, Adult Swim, Zumiez, Smith Optics, and JSkis. Recent hits include concert posters for Goose at MSG and Phish at the Hollywood Bowl.
In 2025, an original Killer Acid painting titled “Results May Vary” was featured in Sotheby’s Contemporary Discoveries auction, appearing alongside works by Andy Warhol, Chuck Close, and Sol LeWitt. Rob described the piece as capturing “psychedelic spontaneity and the joy of creation.”
