:Can you show an example/references of the desired Lisp logo not in the context of LISP machines? A quick search makes me think it is the company logo for the LMI.

::You are right in that [[Lisp Machines|Lisp Machines, Inc]] has a company logo that contains the cons-cell together with the letters "LMI". Note the artistic differences. The cell depicted on the museums exhibit and the one that i suggest for use is quite typical for the drawings in the Lisp literature.
::We're dealing with the problem of determining a logo for a language that never had one in retrospect.
::While we can of course design or select whatever wild picture, now, doing this historically sensible and correct means to for me, to select something that would have recognized as an emblem for Lisp at time, when the language was in wide spread use.
::I believe, there are only two real options:
::# The lisp cell, is i propose here
::# Some S-expression denotation as e.g. on the Lisp 1.5 primer
::So, something like "(Lisp (language))" or so, would be possible, too.
::Now since we're looking for something graphical, the choice is clear, imo. These s-expression drawings are often the only pictures in older Lisp articles or text books. See the Lisp 1.5. manual, for instance.
::To the contrary, the current icon would good for the book's logo, as it was purposely designed as such. So Mr. Steele picked something unique for this book, a combination of Yin-Yang and Lambda symbols, which would not have been recognized as meaning "Lisp". I agree it is nice and unique, but purposely not anything that would have been recognized as an icon for the language. See "The little Schemer"'s cover drawing as another such example.
::I think the designer of the LMI logo picked the cons-cell pretty much for the same reason, i'm suggesting it here. Note some distinguishing features in the drawing of the cell. Most particular, the "cdr", right hand side, reference is drawn on the same level as the cell, emphasizing the list nature of the s-expression.
::This is contrary to a tree-like depiction, which can be seen, for instance in the Lisp 1.5 primer, but this is less common and less iconographic and would not have been recognized as a Lisp-emblem. This one does.
::Additionally, and contrary to the cell in the LMI logo, the dots of the start of the references in the components were typically drawn very small, if at all. So i did my best to replicate a "high quality" drawing, but typical cell image.
