For a better version of this poster, seen in a shop window in San Francisco yesterday, see this Flickr site.
The original slogan makes its appearance at a Canadian liberal convention (search or scroll down).
Not a huge amount of other activity going on, although it still makes its appearance in many personal blogs in many different guises:
- Keep on Writing
- Coping with children
- Keep on making things
- German blog (including the fairly common misunderstanding that this slogan was important at the time! No, I can’t speak German, but Google translate gives me a rough idea)
