A 1991 Nirvana promo photo signed by Kurt Cobain, Krist Novoselic, and Dave Grohl sold for $8,500 last month, topping the rock and music memorabilia lineup at Eaton & Brennan Auctions’ Summer Music & Pop Culture Memorabilia sale. The 10-by-8-inch photo carries all three signatures from the band’s classic lineup and closed with Beckett authentication backing it up.

Key Points

• The photo sold for $8,500 against a pre-sale estimate of $8,000 to $10,000, landing inside the expected range.
• The auction closed on August 26, 2026, run by Eaton & Brennan Auctions, a Shelton, Connecticut-based specialty house founded in 2023 by Tricia Eaton and John Brennan.
• It was one of 500-plus lots spanning six decades of music history in the sale, dated to 1991, the same year Nirvana released Nevermind.
• The lot’s listing was independently cataloged on LiveAuctioneers, which confirms the same three-signature, Beckett-authenticated description.

The photo’s dollar figure isn’t the only reason it stood out in a five-hundred-lot sale. Fully signed pieces from Nirvana’s original three-man lineup have grown scarcer with each passing year, and auction reporting on the sale noted that Cobain’s 1994 death permanently capped how many complete, all-three-signature Nirvana pieces will ever exist. Novoselic and Grohl have continued signing memorabilia in the decades since, but nothing new bearing all three names can enter the market. Every surviving example is a fixed, shrinking pool.

That scarcity math helps explain why a single promo photo — a type of item that music labels once printed and mailed out by the hundreds for press and radio use — can now clear five figures at auction. Most 1991-era Nirvana promo photos never got signed by all three members in the same sitting, since the band wasn’t yet doing the kind of coordinated autograph sessions that arena-level fame would soon require.

Eaton & Brennan built the August sale around that broader scarcity, mixing the Nirvana lot with other high-profile signed pieces: an Alice in Chains group-signed candid photo, a Rolling Stones group-signed guitar, a Beatles-related Paul McCartney signed album insert, and a Bruce Springsteen signed Born in the U.S.A. album, according to the auction house’s own lot listings. The house also folded in pieces from the Chip Rachlin Collection, featuring vintage concert posters and music-industry ephemera alongside the autograph lots.

Founders Tricia Eaton and John Brennan bring decades of combined authentication and consignment experience to the venture, having met in 2018 while both working at RR Auction before launching their own house in 2023. Eaton spent roughly 20 years at RR Auction and three more at Iconic Auctions; Brennan has collected autographs since 1984 and ran his own autograph business, VIP Autographs, starting in 2006. That background shows in how tightly the August catalog leaned into verified, third-party-authenticated pieces rather than looser provenance claims — a detail that matters as much to serious collectors as any single sale price.
