You may also be interested in looking at the (very lovely) silk-screen posters from the 1970s and 1980s produced by The Poster Collective (they are for sale).
A description and a web address can be found below.
“A set of twelve, three-colour silkscreen posters looking at the ideological and economic structures underlying the unequal position of women in society at different junctures in history from feudalism to present. It also shows points at which women have fought to change existing social relations.”
The Collective have suggested that they would be happy to negotiate a substantial discount (or even as a donation) for women’s organizations interested in the posters. Please contact them for details.
