#18 and #26 great choices.

#18 really made me stop and think about the talent of someone to come up with such a literally graphic way to illustrate the message.

#26, the old "battle-axe". I hope you've watched "Suffragette" Egg, it really makes you think about how hard they made life for those women - particularly the working-class women that supported the vote.

Sadly #1 is still so relevant.
