Take a look at these sample ads produced as a portfolio project by Jenny Burrows and Matt Kappler.
These things have been circulating online, originally with the Smithsonian’s name and logo. A lot of folks assumed that they were actually part of a Smithsonian ad campaign. I thought this was some of the best public history PR I’d ever seen. It turns out the Smithsonian wasn’t aware of them until they went viral, and then asked one of the creators to remove the name and logo.
I think they’re awesome. The folks at the National Museum of American History should’ve snapped this up in a heartbeat.
