Entry No. 42 — the San Diego file — filed under: private-collection
J.A. Cooley Museum
Owners Jim and Carmen Cooley built this one-man cabinet of curiosities across roughly three dozen collecting categories — automobiles from 1886 to 1933 parked alongside nickelodeons, phonographs, cast-iron toys, telegraphs, and Kodak cameras — a private collection filling about 10,000 sq ft a mile north of Balboa Park, open daily.
The story
Most visitors strolling Balboa Park never realize that just a mile north on Park Boulevard sits 10,000 square feet of unrestrained mechanical obsession. Founded by Jim and Carmen Cooley, the J.A. Cooley Museum isn't a glossy civic institution—it's a massive private cabinet of curiosities crammed inside a University Heights storefront, organized across roughly three dozen distinct collecting categories.
The centerpiece is a line-up of two dozen automobiles spanning 1886 to 1933, parked wheel-to-wheel inside the hall. But look beyond the early motorcars and the space rapidly fills in with the gadgetry of daily life from the past 130 years: working Edison phonographs, coin-operated nickelodeons, telegraph transmitters, early Kodak box cameras, and racks of cast-iron toys. Today, the venue remains a family affair operated by Carmen Cooley-Graham, preserving a dense, Latina-owned capsule of early-20th-century design right on the neighborhood strip.
What it's like
Stepping off the sidewalk on Park Boulevard feels like walking straight into the high-ceilinged storehouse of an eccentric relative who refused to throw away a single patent between the Gilded Age and the Great Depression. You can wander the narrow aisles at your own speed, but if you ask or catch the hosts on a quiet afternoon, they'll often crank a working antique phonograph or fire up a nickelodeon so you can hear mechanical music as it actually sounded a century ago. Just be sure to confirm their current operating hours before making the trip up from Balboa Park.
The move: Self-guided browse through 130+ years of everyday gadgets, crank a working antique phonograph together, then argue over which of the two-dozen pre-1934 cars you'd have actually dared to drive.
