Here's a (rather small) picture of the poster, complete with a trademark of a bunny holding a needle: https://depts.washington.edu/chinaciv/graph/bunny.jpg
I didn't really find exact dating of it, but given the time of availability of printing technology in China, we can place it to late 12th to 13th century. I doubt Jinan Liu was the only one utilizing this way of publicizing his work, but I wasn't able to find many more. Are there any that survived? What other typical way of advertising were used by Chinese people in this era and shortly before? And how long did it take Europeans to make use of Gutenberg's printing press in the same way?
If I may I would like to add an additional question to the list: Are there any examples of this in European written material pre the printing press?
(op: if you feel I'm intruding, please let me know and I will delete this post no questions asked).
