The latest print edition of Guitar World includes a multi-page tribute to Jim Marshall. The article focuses more on the development of the Marshall line than on the man himself. Honestly, readers of this forum will probably not learn a lot about the history of Marshall that they didn't know before, but the article does include some photographs from the Marshall factory in the 1970s. My favorite is a shot of Jim Marshall in bell bottoms standing in front of two plexi stacks.
The fold-out posters in Guitar World now appear to be sponsored, and one side of the poster is tribute to Jim Marshall and includes smallish photographs of him beside Slash, Lemmy, Yngwie, and other notable Marshall users.
I don't know how many of you actually read guitar magazines in print anymore, but you may want to check out this edition of Guitar World.
