Google cannot redirect you to http://www.abebooks.fr/servlet/SearchResults?tn=Affiches+l%27aristocratie,+ou+journal+aristocratique,+%C3%A0+l%27usage+des+bons+patriotes because the request was invalid.

This might be because the link was created a long time ago. Try your search again on Google. That’s all we know.
