Need any right-wing posters? Go to Political Posters. These run the gamut from issue posters, like an anti-abortion one featuring Rosy the Riveter to general statements of principle of colonial thinkers. There is a satirical one in bright red noting that Che Guevara was an anti-gay, anti-African warmonger. Religious posters are broken out into Biblical posters and those featuring quotations from important Catholic leaders overlain on a photograph of a rosary.
You could base a detailed anti-socialist agenda around several of these quotations. Socialism's basis in resentment is highlighted in several Churchill quotes, and its reliance on fiat money and debt is noted in quotes by Thomas Jefferson, Murray Rothbard, and others.
In several cases, the background information presented by clicking on the links is vital. The quote, "The finest opportunity ever given to the world was thrown away because the passion for equality made vain the hope for freedom" is elaborated at the Right Posters page on the subject. (I've heard many a Lord Acton quote but not that particularly poignant one.)
My single favorite quote is probably, "Generosity is a reflection of what one does with his or her own resources and not what he or she advocates the government do with everyone's money," by Ronald Reagan. It echoes the very thing that most unnerved me about the self-congratulatory rhetoric I heard so often when I lived among the smug leftists of the American Northwest. They were always so proud of how much progress they could create with tax money.
The posters are available in two sizes, 8.5 x 11" and 22 x 17".
