OMG the posters would actually be so cool. Also the t-shirt/mugs that advertise Patti's Plates would be an awesome idea. You can make them look retro and at the same time like the usual kitschy tourist junk that people pick up when they travel. I literally have several of said kitsch mugs from places I have been around the US: national parks, tourist traps, etc. In this case they would be the kind of thing you find in your Aunt or Grandparent's cupboard and immediately ask, "where, and what, the hell is Patti's Plates?"
The sticker idea with the quote makes me think you could also do some sort of campaign poster for John, except that it has a dorky or unflattering photo and was clearly a joke/prank made and put up without his knowledge.
