The Backstory

Step inside the static. This design pays tribute to Frank’s Box — the legendary spirit communication device built by Frank Sumption, the godfather of EVP. Exploded open like a paranormal engineer’s blueprint, every dial, wire, and waveform pulses with otherworldly energy. Printed in haunting white-on-black linework, it captures the strange intersection of radio, resonance, and the quantum unknown.

For believers, skeptics, and ghost hunters alike — a wearable artifact from the frontier of the afterlife.

How It Wears

We print dead things…
on Bella + Canvas tees.

They’ve got that soft vintage feel with a modern fit—less boxy than your old 90s beefy tees. If you're used to those heavier cotton classics, you might want to size up for extra room to haunt.

Got sizing questions? Hit us up. We’re happy to help you cover yr bones the right way.

Every SleepOver design comes from me, Danny West. I chase down a haunted location, a local cryptid, a movie trapped in a well worn VHS, then I design it...human design, right here in Lawrence, Kansas.
