From always incredible Comics with Problems, a few pages from "Who Killed Junior?", an anti-abortion comic book from your friends at Right to Life, circa 1973.
Here's one from the Canadian Party of Labor, 1973.
Blue Wave says "The pamphlet does not argue strictly from a perspective of fetal personhood but it is assumed throughout. The main thrust of their argument is that abortion amounts to the genocide of blacks and the working class, and that 'under capitalism, free abortions are forced abortions.' Many of their arguments presented are the ones we bourgeois pro-lifers use today. Sometimes it’s a little painful to read, because their hearts were in the right place, but they genuinely believed that once socialism was in place, women won’t have to abort! They’ll have everything they need to raise children."
This next one is in Russian; thankfully Viz has a translation!
"I came across this Russian anti-abortion poster from 1925, and thought it was pretty striking. The text translates to: "Abortions performed by either trained or self-taught midwives not only maim the woman, they also often lead to death." It shows a woman talking with a midwife, then a woman in a hospital, and then a coffin being lowered into a grave with mourners looking on. What struck me about the image is that the argument is essentially that abortions are bad because they endanger the lives of the women who get them. The pathetic appeal depends on the viewer's sense of identification with the woman."
Finally some more modern images from a seemingly surprising source, feministsforlife.org. These images are also identifying with the woman, asserting that they deserve better than abortion, that if they only had the resources available they would not choose it. Sounds a bit like that Labor Party ad, above. Also it frames the argument strangely from the beginning with phrases like "Abortion advocates pit women against our children." and "Gone for abortions, almost every one."
