Free Retro-Style Social Media Posters

I stumbled across these awesome Retro-style advertisements for current social media tools on Pinterest (is anyone else sick of reading that as a first sentence for design blogs? hearty har), and turns out all four posters are available as free downloads from MaxiMidia, the company who commissioned them from Brazilian design firm Moma. The posters are 30x45cm, or roughly 11.5x17in, and you can print ’em yourself or upload them to a photo printer (I would use Costco.com’s photo center and pick them up at my local warehouse). After a sharp framing, I think these are gonna be just the thing for my husband’s office at work.
