Emacs Overflowing Kitchen Sink Icon
This is from 1987, in emacs 18.41.
Here's what Noah Friedman, an emacs oldbie, who worked for FSF in early 1990s, says:
[when is the emacs overflowing kitchen sink icon created?]
1987-03-13 16:16, emacs18.41/etc/emacs.icon
That's the oldest timestamp (and emacs version) I can find. It's not in emacs 16.56, which is the very oldest copy I have.
It's still in the current emacs sources, it appears! It's unchanged.
It's the same as emacs.xbm, just in a different format.$ icontopbm emacs.icon | pbmtoxbm > emacs-icon.xbm
and then diffing the resulting xbm file with emacs.xbm shows they are the same bitmap.
