In the promo video for the 30th anniversary of "All Things Must Pass," George Harrison can be seen playing a Gibson L-1 Parlor Acoustic, as evidenced by the footage provided by Kitsu Beatles on YouTube titled "George Harrison - All Things Must Pass 30th Anniversary EPK."

At 0:12 in the trailer for the Netflix documentary Keith Richards: Under the Influence, Keith can be seen playing a 1928 Gibson L-1. He played the guitar throughout the sessions for his album "Crosseyed Heart," including the title track. It is featured heavily in the Under the Influence documentary, and at 13:20 of the film, Keith's longtime guitar tech Pierre De Beauport discusses the guitar, the model's association with venerated bluesman Robert Johnson, and its unique suitability for fingerstyle blues: "it almost takes you there, it makes you play that way - the notes last the right amount of time; the balance between the high strigns and what's going on in the low end, the snap."

Keith also mention in this Instagram post that this guitar is a 1928 by captioning it:

My 1928 Gibson L1. Same guitar as Robert Johnson!

In this video Jeff Buckley is playing on a Gibson L-1 Robert Johnson from 1993/1994. According to Janine Nichols, the original owner of Jeff's borrowed 1983 Telecaster: "at some point I suggested to Jeff that perhaps he should keep the guitar (the telecaster) since he'd gotten so attached to it and buy me a Gibson Robert Johnson model acoustic instead. He then bought a Gibson for himself and kept the tele until he had something custom-made, the guitar he got in the weeks before he died." (source: https://www.mojopin.org/pages/telecaster.php)

Janine Nichols not only had an influence on Jeff's instrument choice with the borrowed telecaster, but it seems Jeff also bought the Gibson Robert Johnson acoustic as Janine said it was a guitar she wanted. Perhaps he had plans to gift it to her later on? Or perhaps he really respected her taste in guitars. The Gibson L-1 Robert Johnson was reissued in the early 90s (https://en.wikipedia.org/wiki/Gibson_L-1) and Janine's suggestion of the guitar and Jeff using it in the live videos would put it at around a 93 or 93 model, assuming it was bought new.

This was Robert Johnson's main guitar during his career. Made of mahogany. Discontinued in 1937, but recently Gibson has made a reissue model with better stability.

In a January 2012 American Songwriter article, in reference to the photograph:

"[Robert Johnson] is holding a 1929 Gibson L-1. Schein says you can tell from “the seven dot markers, an unbound fingerboard, and slanted ‘The Gibson’ logo.” This is the first full-body shot of Johnson, also discovered by LaVere. (Another photo of Johnson and his nephew from this same photo shoot is believed to exist.)

Ren Ferguson, Gibson’s master luthier, says the L-1 in the photo is probably a “studio guitar, not the guitar he actually played.” In 1994, Gibson licensed the guitarist’s name and began producing a Robert Johnson Signature L-1. Ferguson and his team tested a number of L-1s from that era, but ended up making a few modern updates to the original guitar style. Johnson’s L-1 would have been latter-braced, says Ferguson, while now they use X-bracing to give the guitar more clarity and balance.

On the guitars that Johnson and other bluesmen in the ‘30s were playing, Ferguson says, “The notes decay really quick, which is part of what we hear on those old recordings.”

In the user-uploaded photo, Hubert Sumlin is seen playing a Gibson L-1 guitar.

Seen throughout this performance. This Vintage 1920s/30s Gibson guitar looks like an L-1 Flat top but it is hard to identify so could possibly be an L-0 or L-00.

Scrapper Blackwell is associated with the Gibson L-1 acoustic guitar. This connection is noted as #13 on the list at Early Blues, highlighting its significance in his musical career.
